The whole discussion about saddlebags is interesting because I've been looking at them recently. My problem will be because my frame is very small there will not be much space between the saddle and the rack.
Possibly a Carradice Uplift to hoist the bag attachment points a bit above the saddle and a lightweight rear rack to support the bottom would allow a larger Camper Longflap to work for you? It would take some careful measurement, but might be possible.
Perhaps something like this...it hooks into your Brooks saddle loops and wouldn't require a rear rack. Unfortunately, weight is limited to a recommended 6kg:

Can't choose you see.
Dunno if it will help, but here's what I took for my 2014 4-month double-crossing of all Europe, from 9May till 11Sept:
WEARABLE BASE CLOTHING:
• SPD shoes
• 1pr wool quarter-socks
• Undershorts
• Lycra cycling shorts with padded liner
• Long sleeve jersey (sun-protective jersey, SPF 50+)
• CoolMax Buff for my head/face
• Fingerless cycling gloves with padded palms
• Helmet
• Cycling glasses with changeable lenses and Rx insert and rearview mirror
• Alarm wrist watch
QUICK-GRAB CLOTHING (in HB bag for changing conditions):
• Breathable wind shell
• 3/4 cycling tights without liner (to be layered over cycling shorts)
RAIN CLOTHING:
• Rain jacket with hood
• Rain pants
• Neoprene booties
• Gore-Tex "lobster-claw" gloves
• Helmet cover
STORED CLOTHING:
• 1 spare longsleeve "sun" jersey
• 1 shortsleeve cycling jersey with removable "sun sleeves" (I sunburn easily)
• 2 spare Lycra cycling shorts with padded liner
• 1 pair full length Lycra cycling tights
• Medium-weight fleece anorak
• Wind-faced wool longsleeve jersey
• 2 more pairs of quarter-socks
• 2 more undershorts
CASUAL CLOTHING:
• 1 airweave t-shirt
• 1pr. nylon cargo pants with zip-off legs to make casual shorts
• Billed ball cap with detachable cape to shield my neck from sun
With the above, I worked 10 days in Turkey, rode the rest of the time and spent time with friends and eating in restaurants and exploring towns on foot. For restaurant dining (yes, even in 4- and 5-star hotels in Eastern Europe, where they were very inexpensive...I once borrowed a tie for my cycling jersey when it was required!
), I wore my black SPD shoes, my charcoal cargo pants, my t-shirt under my nice wool longsleeve jersey and...got by fine. When someone would occasionally mention my attire, it was always in a pleasant way and opened the door to some pleasant conversations and even friendships that have endured since.
Temperatures ranged from lows of 38°F/3.3°C in the mornings a the start and end to as high as 114°+F/45.5°C ambient (hotter on the road). I also had periods where there was a lot of rain.
I was never really cold. In 3.3°C temps, I added the 3/4 tights and the wind jacket and was fine so long as I was working, and added the midweight fleece or wool jersey if I knew I was going to stop and cool down for any length of time. The secret was to add layers or remove them as needed.
I generally take enough clothes so I will be warm at the coldest expected temperature if I don *everything* (and I mean every.thing). This works pretty well even in the desert, where I can expect a daytime high/nighttime low temperature range of about 80°-95°F (or from 114°-19°F/45.5°-
-7.2°C). It is at 7.2°C I put on *everything* and generally also wear it inside my down bag and silk liner in the tent. A person really feels the temperature difference when the sun goes down and the winds pick up in America's Great Basin.
I used to wear cleated (road) cycling shoes and took some casual clogs for walking (Merrell Breeze II, support of a trainer, easy to kick off and also worked as shower shoes:http://www.englinsfinefootwear.com/merrell-mens-primo-breeze-ii-available-in-multiple-colors/ ), but now I just take my SPD cycling shoes and wear them for most everything. For showers, I just wade in and then dry my feet after and apply antifungal cream prophylactically. Never had a problem. For nighttime bathroom trips when it is raining, I wear the SPDs without socks so if it is wet, my socks stay dry in the tent and the shoes dry out by morning.
This is generally as much clothing as I take at any time for longer tours. For shorter trips, it is much less...usually just a spare jersey and riding shorts and one spare pair each of undershorts and socks with arm warmers and maybe a light fleece or wool jersey and my 3/4 tights (one of my most versatile cycling garments...warmer than shorts alone and keep my knees warm, but with enough leg uncovered so I don't overheat).
One last suggestion: Grey socks. They don't show road dirt like white ones do.
There's a few more tips and tricks I've found for extended desert use, but I will PM them to you.
'Hope it helped to see someone else's list.
Best,
Dan.
