Besides programming, I would just be careful with technique and cueing yourself.
I still have to put forth a decent mental effort on every set to make sure I'm hitting the squat the way I want to, or at least coming close. Doing too much switching could hurt that rhythm. And I want to get a decent amount of "practice" in, so I tend to do a lot of work. For me I'd rather just split up days, which also helps to keep my legs fresh.
You don't know until you try tho! It does sound like it would be a fun work out.
