What I hope the concern will be is that it's generally a good idea to keep The Price Is Right and Let's Make a Deal from looking too much like one another, and any kind of raised audience (especially if TPIR is still using distancing pods) will look a lot like Deal's setup. Additionally, when Wayne selects a particularly energetic contestant from the top of the seating area, he sometimes has to interrupt their enthusiasm by cautioning them to be careful as they make their way down. There have been TPIR contestants who have managed to fall down on a ramp -- I'd be worried about forcing them to contend with stairs.
Also, there's something subconsciously significant about the winner of a One Bid being permitted to ascend onto the stage.
