Ok Vickie here is a first draft.
Concept is to have 1 overflow drain, on one side with a 1 1/2 BA as the drain with a duraso in it. The opposite side will be a sleeve to house the return line. Personally I think it should be in with the drain overflow. On your oceanic sump, leave the container in but gut the unit. Toss the top plate with the two inputs and replace it with an acrylic plate with one 1 1/2 BH dead center. On the inside of that attach a filter sock holder for when you want to polish the water (link attached). Put your skimmer in the sump between the baffles and the box compartment. As per a return pump look for something that is going to give you about 1000 gph and use it for surface braking flow only.
On the closed loop the concept is to have a Motorized ball valve, but instead of side to side lets go top to bottom. The water will come from the two 1 1/2 inch BH's drilled inline to a point where you can access them for cleaning. they drain down into the CL pump, form their the pump goes directly into the MBV. From one side of the MBV use 1 1/2 flex to bring the water to the upper 1 1/2 manifold at a Tee point then their will be 6 out puts. I have more out puts up here as it is better to have a little less flow but more flexibility for coverage area. The other end of the MBV goes to a lower manifold about 2 inches above the bottom of the tank. Again it attached to a Tee and then spreads out to the other outputs. The out puts are tee's that are reduced to 3/4 fitting to go into the 3/4 bulkheads (the ends of the manifolds are elbows) on the inside of the tank on the outputs are 3/4 loclines. On the lower loclines attach Y's to each output to double them up and then fans on the ends of them (look to nikkis tank for concept) .The reason their are only 4 outputs on the bottom as you will need more force to blow detritus off the bottom. This flow pattern should give you a very good random pattern, with a lot of flow blowing the detritus to the coast to coast overflow. Anyway thats a first draft, we can get into details after you or the hubby have any questions.
here is the disk I was referring to
