I think what you are saying is you will be over your limit!
From personal experience, flying from Turkey to India, India to Singapore and then from Beijing to Munich with 2 eXp's you need friendly check-in staff who are prepared to waive or reduce any excess. We found looking pathetic helped, and from Beijing to Munich we paid no excess they told us to take our pannier's as hand luggage (Air China.) Turkish Airlines were quite good too. But Air India were just a joke.
As for the pedals, we took ours off but put them in a pannier and not one airline questioned it.
It really depends on the airline. But if you are over your allowance, then you are over your allowance!
