I don't think in our pre-fallen states such a thing would have been an issue. We didn't know sin or pride or anything else that separates us from God.
But... you may have a point in that they had not yet made the conscious decision to NOT sin, which would have sent the human race in the other direction. Then what would it have been like? Would we still need to rest for 1/3 of our existence? Then again, would it matter? We'd never die, so we'd have all eternity to pursue such projects.
Ugh.... bro, stop throwing out these stimulating thoughts. I'll be here all day
