I think the only possibility to look at this question without having too much logical flaws is to assume that Mario and Nintendo existed exactly like they do, but this game wouldn't have been Super Mario Galaxy but would have a new character starring.
I think the game would have sold very decent too if that would have been the case, somewhere between 3 and 5 million which would be awesome for a new franchise.
If the game came from a third party publisher though it probably would have struggled to reach the million because it would have been the "platformer Okami" then.
People know what to expect from Nintendo, so they rather buy new IP's from Big N instead of new IP's from third parties.
