if your doors are power, you will also have to w/ pulling the kick panel undoing/reinstalling the harness plugs.
if manual, just delete the door speakers & reroute somewhere else.
another option for tube is half doors. when my buddy still his Grand Cherokee, we cut down stock doors for off-roading use. we got 4 spare doors & gutted them, minus the latches. cut the tops off. sectioned a section of the inside out, then folded part of the outer over & in, then tack welded in place. grabbed some scrap metal to use as fill in pieces where needed. drilled a small towards the dash end of the door. took the latch rod & looped the handle end. inserted the latch end through the hole & reattached to the latch. the hole keeps the rod located 7 the looped end gives you a finger pull to open the door. the doors were now light enough to install by yourself. would still need help w/ the loaded doors.
could try this: if your good w/ welder, cut the hinges off your doors & body. install a set from a newer vehicle. you lower the doors onto a pin, fold a flap over & install a 10mm bolt to secure the door in place. go to a j/y & look @ newer gm vehicles & you'll see what I mean. the question becomes, if placed in the exact same spots as the old hinges, will the door still open the same # of degrees?
it's a thought that's been bouncing around my mind for a few years, but don't have the tools or better knowledge to attempt.
hope something of this helps or @ least plants a seed for thought
