You should, they build those things in Everett yah know! :)

Back on this, how easy is it to induce a stall a cruise at FL 41. Converting TAS to IAS, 120 KIAS gives you 208 KTAS. .8 Mach, I would guess would give you a pretty good margin still.

It depends upon the aircraft and turbulence. For an aircraft to be certified to an altitude at a given weight, it must have a 1.3 g limit in most cases. From what I am reading though, this sounds more like an engine/fuel issue than a wing issue. The limiting factor in most aircraft is not the engines, but the wing.
