Yes you can. I just put a similar setup in a jeepspeed cell. Sorry, forgot to take any pics before I dropped it in.
If you can't make the plate yourself, buy a steel rci plate, or even better a jaz plate with the removable fast fill neck. I can cut one on the cnc as well if you pm me. you can buy the 16 and 24 bolt seals for the plates from summit as well as the ring that goes inside the cell that holds the bolts if you don't already that with your cell.
Buy the walbro 255 pumps from wide open design or summit. You can get most of the fittings from either of them as well, or use hydraulic fittings. Get the socks for the bottom of the pump(s) or add walbros.
Buy some of these to pas the wires through on a bolt

Weld some thing to the bottom of the plate to hold the pumps on at the right height with hose clamps. It's not the easiest thing to make yourself, but you can save some $$ and it aint rocket science.
This is what I built to fit in Cole's existing AL cell.
