I'm not too sure these statements really go together.
From reading the posts you've done in the past about putting your house rules up for review, I think you may have fallen into a rules bloat trap. I've seen it quite a few times, even fell into it myself before and scrapped a whole lot of house rules when I realised I was doing it.

Playing about and adapting your own set of house rules and homebrew is a good learning experience, but another part of the process is learning when to cut back and keep things simple and easy for outsiders to understand.
Trying to have a set of class specific rules AND a set of multiclass restriction rules at the same time, both with the stated goal of fixing a perceived imbalance, it just sounds like unnecessary over complication. Either one set of adjustments works or it doesn't. If it works, there's no need for an additional set of adjustments, and if it doesn't then don't include it with testing the next set of house rules. Keep the bloat down.
