i Love the display back, gen owners can order display backs for $3XX dollars, and many do. as for the domed crystal i have a hesalite one from my Alpha speedmaster, looks like it might fit, but i dont wanna try and find out ruining my watch in the process... If the crystal bothers you then the sub dial spacing would be worse. If you're going for as close to gen as possible get the speedmaster "reduced" rep. But as it stands the speedmaster rep is STILL one helluva of a nice watch, just gotta accept the differences.
