Saw it when I was a kid and has been in my retina since then.
Would such thing work? What considerations to take in account, limitations and calculations for the capacitor and inductor to provide 120 degrees phase shifts ?
No, it will not work.
A Perfect Capacitor or a Perfect Inductor can give you Only 90° Phase Shift - Leading and Lagging respectively. It will be less when you have something else in series - in this case the motor coil (Resistance + Inductance).

I'm sorry to burst your bubble, but it will work.... My father built a three phase lawnmower ( Christ knows why )... Anywho!! it worked just fine he ran it off 240vac. He used it for years.
Are you referring to a 120° phase shift or making the motor spin?
If former, you can't burst that bubble
If latter, there is no bubble to burst

He asked whether the circuit would work.... The correct answer was yes!!! whether it was efficient whilst running wasn't asked for...
And the 3rd terminal..... ?My drill press was 3 phase and ran from 1 phase for ages.
Only it didnt have the choke, just the cap.
I am in north central LA, where were you back then?Interesting, I haven't heard of a wild leg since I was in Louisiana.
