I want to redo my sump but have the problem of the stand being very akward. It only fits 10 and 15 gallon aquariums. I've been contemplating an acrylic sump but am missing various tools, space, and craftsmanship

, and I really just don't like working with acrylic. I was wondering if there was anything wrong with my setup (see pic). I don't know which is harder, explaining or drawing...or explaining my drawing.
I was planning on:
1. Splitting the overflow to feed the fuge. The overflow is about 600 gph, so about 100 to the fuge?
2. Putting bulkheads with overflow's on the side of the skimmer tank and fuge, or should I just drill the bottoms?
3. Should I maybe put two overflow's, one on each side and join them, then split, or even one for the fuge and one for the skimmer?
