I was thinking about adding an external box to the back of the intank over flow so I could fit three 2" lines on mine. Since what is really restricting us is that 45 bend at each end of the over flow and the distance between the front wall of the over flow and the back wall.
I think a external box on the outside could hold all three line and also the return. Plus it would give the benefit of being able to put the bottom of the 90's on the siphon at the same level as the bottom of the teeth in the internal overflow, which I don't know if that could be done with running them inside the overflow with 2" 90 elbows.
