So my .02 from a bit of experience, sort of.
Get the A/C done and then stop. Your Blazer it rather nice, you are headed down the path to the dark side. Buy that other one and turn it into a buggy of sorts. Then turn yours into a rig that can tow it well, by stealing the true wheeling parts off of yours aka big tires, lift? and stuff.
Had my for-sight been better I would have left Twinkie as she was fixed a bunch of non working little things and then built a four seat or so, buggy. I did how ever make the decision when I even had another one to do it to. When in reality I could have built a really nice seven passenger tow rig and a cool buggy at the same time. Now I have a rather nice, not square body tow rig and a nice buggy of sorts, just went about it the path of the dark side.
You are right on track with what I'm thinking.
This one is getting fuel injection and AC and possibly gearing, this is my around town, light trails, towing rig, I want comfort and new tech on it.
I will get a beater that I can hack up and flat tow like a jeep behind this one. I have lots of spare parts that I could stick on a buggy. I'm actively looking for a decent and CHEAP base vehicle to chop up.
