IME, some of Mesa's pots have custom tapers. Other tapers may change the way the controls interact. It may be worth the cost/effort to get parts from them. The manual usually has part numbers in the back for the different pots - at least the newer ones do. And their customer service is top notch.
Swapping pots is easy in most of their amps (don't buy into the PCB baloney). Flying leads, well made components, strong chassis'. The ones I've worked on have been very, very serviceable. Good luck with the project.
