I would say: yes, as long as the "original equipment" manufactured is close enough to the N900's hardware that it doesn't require recompiling the proprietary parts - because the Hildon Foundation still doesn't have access to their source code, only redistribution rights for the binaries.
It will not be much of a problem, though. Create N900's clone which is waterproof, shockproof, dust-proof, and has inductive charging, and you will have at least some of the customers hooked. Manufacturing N900 exactly as it was would have likely been profitable; manufacturing N900 with improvements will be profitable for those who attempt it.
Just don't expect me to backup these claims with my own life. However much I believe them, my perception of space, time and world in general has been known to differ from reality.
Best wishes.
