In my opinion I don't think it would hurt as long as the playability of the guitar where both good. If you use different type of guitar it may take a bit longer to get used to them. (muscle memory). A drastic difference say going from a dreadnough to a classical guitar might pose longer adjustment time.
I say it would be an advantage..
One possible problem I do see would be storage if either home had drastic changes in temp and humidity..
Good luck and beware of GAS.. Guitar Acquisition Syndrome, Also know as Gear Acquistion
Syndrone.
