Unfortunately, none of those would work well.
A proper fix would be to reweld the aluminum and machine it down to tolerance.
Unforunately, that labor intensive and requires special machinery to do properly (or expensive).

Your rotor housings look like you use some type of sealant on the o-rings?
I don't like to use RTV types of sealant on those o-rings, but it's the only option you've got outside of the more expensive option mentioned above.

Luckily, it's on the outer o-ring, so the stress is not as bad versus the inner o-rings; you don' t have to worry about the inner combustion chambers!
