For initial pool sessions I wouldn't worry about using a boat similar to the one you own. Find one in which you have a fairly snug fit.
When you initially get in a snug-fitting boat it may feel like you will have difficulty getting out of it upside down. I think you will find that when you are inverted, pop the skirt and everything is wet, you will be able to slide out just fine. The water lubricates everything and gravity is more or less working in your favor or is not a factor, since you will be essentially weightless in the water.
A snug fit will allow your lower body movements to be more effectively translated to the boat for bracing, rolling, and bow rescues. Once you have worked on these in the pool, you will be more comfortable doing the same with your boat in protected, outdoor waters.
