I wonder if the spark plug hole is replaceable? I would call a honda dealership and tell them what your problem is and see if they have anything for you. If you do need a new top end check ebay. Hopefully you’ll find something that won’t break the bank!

I went the helicoil route in an outboard several years ago and never had a problem with it. Now I'm just rambling but could you find a plug with larger diameter threads but the same thread length and rethread to the new diameter? I believe I've seen plug charts showing diameter and depth.
