Not sure what the prospects would be of selling your mod. I would think most modern Porsche buyers would prefer a Porsche motor (whether stock 2.7, an S or a 996 upgrade) vs a sbc or rotory swap.
Since you mention this is a "shared" car for a short term ownership, a used Boxster or 996 motor would be the best. 996's came with TIPS too. Infact, 300hp with a TIP can be quite nice.

A rotary swap??? Every RX7 owner worth his salt can't wait to get rid of that twin-turbo nightmare and stuff an LSx in there! 
I can't imagine choosing to do the incredible amount of engineering and fabrication necessary to fit a Mazda rotary and gearbox into a mid-engined Porsche, and then wind up with... a Mazda rotary and gearbox in a Porsche!
Mind you, I'm a big Mazda sportscar fan (have owned many), but that's just the morphine talkin'.

I once considered the RX8 because of the rotary engine.
This is really a jewel when looking at it from engineering perspective (but may be not from a mechanical point of view).
Too bad honestly.

I have over 700,000 miles driving rotaries, including an ITS RX-7. Some of my cars had 200,000 miles on them when I sold them. I never had an engine fail. One of them, an 89 convertible, had 173,000 miles on it when I decided to restore the car. I went ahead and had the engine ovhauled. The engine builder offered to put new bearings in or leave my originals in since they were broke in. We decided to keep the originals. I am not saying they are the greatest, in fact they can be temperamental. The turbo ones required cool down, and the RX-8 need high rpm and throttle to avoid carbon buildup. If you don't, carbon builds up and can cause apex seals to stick and slam into the rotor housing, cracking the seal. This has been known to cause engine failures.
Measuring the engine compartment, there is plenty of room for a 13b, but a 20b would be a tight fit.
We are going to rebuild the boxter engine. I started a new thread that I will post on as we figure what actually failed in the engine.
