Would 650b conversion for the ASR5 it be as simple as redesigning the rear triangle with a bit longer chainstay?

As it is, the BB is pretty damn low with 2.2 tires. I don't run fat 2.4's on this bike but have thought about it just for a little more pedal clearance.

I like a 140mm fork on it but with a 650b f/r, I could deal with riding a 120/130mm fork to reduce the added BB height from larger wheels.

Of course, no company wants to sell half a frame so this will probably never see the light of day but figured that I'd ask. Yeti will have to keep building rear triangles to keep a warranty/crash replacement stock on hand and the 5c doesn't seem to be leaving the line-up.
