For fans of alliteration you can have Switch Saturdays (or Sundays) where everybody on your boat has to ride switch the whole time. In short you just have to make yourself do it. It's almost as bad as learning how to wakeboard again but once you do it long enough it will be almost as easy as riding regular. It took years for me (I've been wakeboarding for 20 years) but something interesting happened. I got to a point where I was learning how to jump all over again switch and I actually started jumping higher switch than regular. I then applied the technique I learned riding switch to my regular jumps and those got higher too.
So, I'm not aware of any shortcuts. Go out with some freinds who you don't need to impress and ride switch the whole time. Repeat that until you feel comfortable.
Here's some switch air for you:
