I flew multiple aircraft in the same class and category while doing my PPL and had no problems. At this point there's old enough that's there's nearly as many differences between two C-172s as there are with a C-172 and a PA-28. Yes, it took me more than 40 hours but I blame that on scheduling, not the aircrafts.
