Why wouldn't the superlift hardware work?
Yes, it has a lot of "extra" parts in the kit for dropping the front differential which wouldn't be needed for a 2wd, but the parts for dropping the LCA's & t-bars should fit, right?
The superlift website has a complete parts list (in 4 groups) and instructions, so with a little studying it should be possible to put together a list of what you'd need - checkit...
Of course, they might not SELL you only the 2wd parts, or it might cost less to just buy the whole 4wd kit... On the other hand, they might be very helpful and reasonable - who knows!
Aside from relocating the LCA's & diff, the other part of the kit is the taller spindles, which ARE different from 4wd to 2wd... I *think* you could use the 4wd stuff, and without the CV shafts it wouldn't matter if the hubs were locked or not. (4wd guys, is this correct?)
The other option would be to use '02-05 explorer/mountaineer spindles, which are taller than 1st gen ST spindles, like the superlift ones. The upper ball joint studs are threaded instead of grooved like the ST, but that might be fixable simply by looking at a (moog, raybestos, etc.) catalog with detailed drawings and finding one with the same stud as the threaded type and the same housing dimensions as the replacement ones for press-fit UCA's. Or call BTF Fabrication and see if they'll make a set of ST UCA's with uniball studs to fit the newer spindles.
I'm not saying it would be as easy as using a turn-key kit with full instructions, but it might cost less, and it should be do-able.
But the body lift would be waaay cheaper & easier. ;-)
Edit: just re-read & saw you are looking to do BOTH suspension lift & body lift - is there a certain tyre size you want to run, or do you just want it as high as possible, or...?
What do you have in terms of tech skills, tools, and budget?
Also, if anyone knows of specific problems with the "pieced-together" lift method idea as described above, or other needed parts (outer tie-rods?), PLEASE chime in! I'm a newb to this and looking for something similar myself, so lets see if we can figure something out...
