About the only thing to do is to re-plumb the outlets to get them closer to the sidewall.
You could get a waste 45º elbow and an extension and move the terminal end out so it'd be easier to hook up, and then get some electric valve operators so they'd be easy to operate and that way you wouldn't have to redo the plumbing.
Camco makes a clear 45º fitting. You could also get a waste extension or two. They commonly make 10" and 8" so you may need more than one.
