As long as there would be a significant advantage (in-game currency-wise most likely) to use your faction's variant or the stock one, I'm okay with people who want to spend a small fortune to get a different faction's one.
Complete recustomization of a given Mech chassis would be something different though. If one could easily turn the Warhammer from the example into a LRM platform just by fiddling around some in the MechLab, that would probably be not so great. Because that would effectively mean that it is in fact some kind of OmniMech. Which does fit neither the "BT lore" nor really versatility of gameplay in the long run. That would just lead to everybody and his dog using the same 5 or 6 cookie-cutter rebuilds and ultimately lead to stagnation and boredom. Don't think that'd be a good idea.
Regarding the acquisition of specific variants there could also be the opportunity to tie that somewhat into the meta-level of "Galaxy Conquest". If your faction/regiment/clan/unit manages to capture and/or hold a certain territory/planet, it makes perfect sense that they would get additional access to an extra variant or two which are more common in that region. Would also make that whole conquest stuff more flexible possibly, as I can very well envision units going on a "shopping raid" because they want to get their hands on some new Mechs.
