Adding windage tray to assembled short block

I have my stock 5.9 Magnum short block rotating assembly (crank, rods and pistons) all put together and torqued to specs and have decided to add a windage tray. Can I install the tray without pulling the whole assembly apart? I'm using the stock bolts on the mains and have bought the Milodon studs to add my windage tray. Can I get away with breaking loose all of the main caps, installing the windage tray studs and torquing everything back to specs?

Thanks!
