Will it Work? Making a Honda GX390 / Clone Compatible

A few years back I did a video series on a trashed NAC NKG generator (NGK-7000H). I got it running and making power, but when almost done the stator failed. I harvested the engine and put it on a shelf thinking I could use it at some point. Its been on that shelf for over 2 years. A lot of generators have come into the shop that needed an engine. The Honda engine has the standard Honda clone tapered shaft, but a non standard bell housing. Because of that, I cannot use it. Will a Honda clone engine end cover/bell housing from Generac fit an OEM Honda GX390 engine? I hope so because that will make the Honda engine clone compatible. Engine cover came from this generator: https://www.youtube.com/watch?v=W8bh-Vg-tiE&list=PLoj6DvbhMTzslNXZ6C4E2jcZW1TDzCjdQ&index=26 Here is the video series where this engine came from: NAC NGK Generator Playlist: https://studio.youtube.com/playlist/PLoj6DvbhMTzteT1KT4km_vsaJDke96-jR/edit Generator Model Failed Engine: GP7500e (0059432) End Cover: 0G84420227 Crank Ball Bearing: 0G84420117 Counter Weight Ball Bearing: 0G84420118 I no longer use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner. Harbor Freight changed the recipe. The bottle previously stated "NON-CORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors. Recently I have been using Simple Green PRO HD with good results.
