For the return you should be able to reduce pipe diameter one size to make a little more manageable after the top Tee, build a manifold (such as like here) to even out flow and with multiple outlet not have a great loss.
RC calculator might be a guide.

Do yo mean for the closed loop return or sump return? I think your talking about the closed loop right?

If you are, you say it should be fine to reduce down to a 1.5" PVC after the first "T"? That may help out a lot actually. In a way...Its kind of a weird situation and heres why...

The closed loop pump has a 1.5" outlet. The bulkhead that the return is going through is 2". I figured this is good because I always hear its good to go up a size anyways. So like I said, I figured it would work well if I went from 1.5" at the outlet to 2" right away and then through the bulkhead and used a 2" manifold. As I said though, the 2" manifold is a bit tricky to manage. So your idea to reduce down to 1.5" seems good. Maybe I should just use to reducers right around the bulkhead? So basically the pump goes to the bulkhead at 1.5" and goes through at 2" and then goes back to 1.5". Seems kind of weird but I can't change the 2" bulkhead at this point. Any thoughts???
