Serpentine/Power steering pump help

[DallasTxImpalaSS]

I ran across a deal on the brackets and accessories for the big block serpentine conversion. I have the tbi 454 with hydro boost. I have the power steering pump with the remote reservoir canister and two return lines one from the cooler and one from the hydro boost. The pump that came from the new motor is the newer style with only one return line. Could I swap the pulley and use my old pump with the reservoir. It looks like it lines up but I would have to run one of the return hoses under the frame or it would be in a very tight bind. Or could I use a tee to connect the two return lines to the pump, I am not sure how much pressure are on these two hoses. I am trying to avoid buying a whole new pump as I just bought this one a few months back. Any help is appreciated.
