Is this a realistic project?

Guys, I really have a lot of experience with old skanky s'posed to be mid-time engines, and sometimes it's Okay... It often isn't. It can seem okay for a couple three hunnerd, and usually when the problems show up they just bite your wallet, but sometimes they bite yer arse. This is an old cherokee engine for sure. Good motor, but it might have a dud oil pump. Aluminum or even sintered. I think it will need a new crank gear and a one piece cam wouldn't hurt. Tear it down, recertify/update your crank, use a new cam/lifter kit, new pump kit, new pump body (probably), have your jugs evaluated for a re-do if you are minimizing or just get new ones. You'll run longer, sleep better, leak less, die less soon. Or if you sell it you won't hand off a dudster to some poor dude. 30 years is a long time for an old sittin' around cherokee motor.

Oh, yeah, it may also still have the skinny exhaust valves installed, doubt it but you never know.

I bought a engine that was overhauled 15 years ago and pickled, been sitting ever since. In the course of getting it ready for my 8A, I have learned so much about it, that maintance down the road is going to be alot easier. Whatever you decide to do, I like your route.

The engine doesn't come from a Cherokee, but from a French Socata MS-892 Rallye.

I know the full history of the engine and have been able to talk to the A&P mechanics who was in charge of its maintenance and pulled it off the plane 30 years ago.
It's been preserved all that time by 2 different owners who never ended their homebuilt project and decided to sell it.
I have a quite strong experience in rebuilding motorbikes and English cars engines and I'm surrounded by at least two real aircraft engines experts who live a couple of miles from my workshop.
I had the engine for a VERY good price, so even if I have to do a complete overhaul, I'll still be within my original budget and I'll have learned a lot about engine building and maintenance, which is also my goal.

is nothing more than a teardown and dimensional / condition inspection to ensure serviceable limits. It is prudent to bring high wear parts up to new tolerances. Lycoming has a 12 year calender limit after an engine is put into service. My two concerns are internal corrosion and old rubber. Spend a couple hundred bucks on the rubber and gaskets, get a manual and tear it down, It's not that hard.
