4x4 auto to manual conversion question

I know this subject has been discussed a few times on here, but here is my situation. I have 2 vans right now; a 4wd auto with an iffy transmission and an 2wd 5-speed with a bad engine. I am selling my house and moving in a month and will have to get rid of my 2wd as its essentially a parts van right now. Would it be worth grabbing the manual transmission, shifter and linkage in effort to convert the 4wd van down the road? From what I've read the transfer case has different size input shaft, so that would have to be sorted, but could the rest be feasibly swapped around? Also, if someone wants what is left of my 2wd van, it will be available pretty soon, located in Greensboro NC.
