Sure, there will be the question of stability with the large-frame speakers, there will be an acoustic effect as the speakers are lifted slightly higher above the floor, and MC's statement about problems with precise positioning on carpet is true enough. My opinion is that the positioning knowledge OP gains will more than offset those issues.
At the end of the day, I wager OP will have moved his speakers around more than many listeners who experiment with position and orientation. OP will be able to dial them in for his room, source, electronics, music preference, and so on. OP is tweaking and evaluating, and that's what the quest is about.
