Lighting

If I have a FRAG tank that is 48x48 ( LxW ) and put a combo MH/T5 light fixture over the center will the lighting be ok for LPS and SPS? That way I can kill 2 birds with one stone. I know I would be better off with a MH rig on half and T5 on the other half but looking to save a few pennies.

tks
