I am tearing down walls to remodel my kitchen but one wall has a return air duct near the ceiling (no actual ducting in the wall, it's hollow between the studs.) There is only one other return air duct in the area (about ten feet away) but the room will be very open once the walls come down. There will be no interior walls left so my only foreseeable option is the floor. Can I have return air duct on the floor? Also there are cathedral ceilings in the area; no attic.

Amber - Warm air rises. That is why its high on the wall to maximize cooling efficiency. If you move it to the floor it may not do such a good job at keeping things cool in the summer. Moving it to the floor is better that eliminating it altogether. It wont hurt anything it may just make your system not work as well as it currently does.

Welcome Amber:
Your house sounds like it will be wide open when you finish with the walls. One return air filter-grille should do the job very well. The additional returns in seperate rooms are to keep those rooms in the loop of air; no walls? no need for additional returns. I hope this helps.
