If you have a local Moots dealer, TALK TO THEM! You're ready to drop almost $10k on a bicycle, they better damn well help you get precisely what you want.
As for it being a lifetime frame, yes the frame will probably last longer than you. The better question is whether the frame will be equipped with the correct dropouts/brackets/attachment points for as-yet-unknown future bicycle technology. Could it be adapted/updated for this? Maybe. These are questions you should ask the Moots dealer, since you're fortunate enough to have one nearby.
