I get the swap, a rotary can make power cheap naturally aspirated, a port job with a dremel along with properly sized intake and exhaust and a good carb can absolutely give a 4AGE a run for it's money dollar for dollar which needs a lot more work on cams, timing, compression ratio, and tuning to make power, things on that are a lot harder to homebrew than the wankel.
As for 13B vs 12A that comes down to whether or not you want to work with carbs or fuel injection, with the caveat that fuel injection from the 80's is not exactly the pinnacle of user friendliness, pretty sure there's a minimum 1 post per month about a surging idle on a NA 13B over at rx7club.
Not to mention the first generation RX-7 he's got sitting there has archaic suspension compared to the AE86 (primarily live vs. independent rear end), he got a motor he knows how to work with in an improved chassis. (Of course you could/should just pick up an FC but I'm no mind reader).
If I came across an AE86 that some kid blew up as a roller for a couple hundred bucks or the low teens and I had a 12A laying around with enough parts and know how to get it up and running you bet your ass I'd do it. 150 horses estimated at the crank on a stock port 12A is not unheard of if emissions is not a worry with the right intake/exhaust/carb setup, that works out to be more power at the wheels than the US AE86 had at the crank (~112 hp). With an aggressive port job and the right carb setup you can be looking at 200+ horses at the crank.

All that being said they say the most surefire way to end up with a money pit is to buy somebody else's project car, they're selling it for a reason after all and you'd be foolish to expect that you could drive this car long term without a hitch. The only person that should buy this is the person who wants it, don't get persuaded by anyone, if you had the idea on your own, if you went out and were pricing out parts to do it this is likely a jackpot, everyone else should probably stay away.
