I think you should technically be able to use the publicly available functions to fetch the wallet's master key and derive any address type at any derivation path you want but I don't think it is possible to make it part of the wallet file itself. Because that would require modifying the wallet file (something that a plugin should not do) and that's something that would corrupt the wallet because it is designed to have a single "type" that the code uses to derive child keys. To change this last part you'd need to change the code.

So that's it. Unfortunately, the Electrum developers will never add such functionality, as they believe address types should be separate. I'll just keep using Bitcoin Core, even though I need to have the entire Bitcoin network synchronized.
