Light and Flow for a 54 corner

[salmon alley]

I've got a 54 gal corner acrylic that I'd like to set up with a combination of SPS in the upper half and LPS in the lower part of the tank.
I'd like to get some recommendations regarding lighting and how to achieve appropriate flow, especially given the footprint and height of this tank.
I'm not a fan of the all T5 look, so that leaves either combination MH/T5, solo MH, or LEDs.

Thanks very much!
