All congratulations to you and Chris, jags!
In considering What's Next...have you considered a Club Tour?
As for touring on an Audax, no help I can provide personally, as I'm at the Heavy Lifting end of the spectrum with my Nomad Mk2.
The Thorn brochure (
http://www.sjscycles.com/thornpdf/Thorn_Audax_Mk3.pdf )speaks to this matter pretty clearly...
Versatility
Whilst the Mk3 Audax excels at light weight touring (less than 8Kg), the frame is strong enough to cope with medium weight touring.
If necessary, it will carry up to 31Kg of luggage.
It will carry 20Kg on a suitable rear carrier - if you need it to!
It will carry 5Kg on the forks .
It will carry 3Kg in the bottle cages and it will carry a 3Kg bar bag.
The Mk3 is supplied with a pair of high quality, competition weight Cro-Mo forks, with cast crown, complete with stainless bosses for mudguards and lo-loader carrier. These forks are designed for comfort, with
narrow tyres, at high pressures, therefore it is important that you do not treat them as “full-blown touring forks”, they have a maximum luggage limit of 2.5Kg (per side).
Note, for medium weight touring, due to the fairly short wheelbase, if more than 10kg is carried at the rear, the bike will handle better, if some weight is carried in front lo loader panniers.
Jags, if you wish to do some touring, it might be wise to consider buying the original steel fork as well as the carbon one, allowing for maximum versatility.
I did come across an interesting account of lightweight touring in a Thorn Audax Special Edition (looks like the now orange one Steve has, but in its original livery) on CGOAB here:

http://forum.ctc.org.uk/viewtopic.php?f=5&t=7677&start=0I'm sure owners on the Forum can offer further opinions. John (Leftpoole) has owned a number of Thorns including the several Audaxes and a Club Tour and could speak to their comparative fitness-for-purpose.
Best,
Dan.
