Help using software wallets as co-signers in a multisig (bitcoin core signer, electrum signer, sparrow coord)

Hello everyone

I wanted to create a multisig for example 3 of 5 using sparrow wallet as the coordinator.

I wanted signers to be mix of hardware wallets and software wallets:

- hardware wallet

- hardware wallet

- hardware wallet

- bitcoin core

- electrum

But i'm having a lot of difficulty getting the software wallets to work with sparrow (or being confident/comfortable that it's working as intended and won't have issues)

My issues and concerns:

- Electrum when creating a standard single sig gives a derivation path of m/0h (not the m/48'/0'/0'/2' derivation path that sparrow is looking for) and a zpub (not an xpub).

- I asked AI and it then kept telling me that's wrong and to create a multisig wallet in electrum but just don't give the xpubs of the co-signers. But electrum forces you to add co-signers and then AI said, just give it fake xpubs! I'm not sure/confident this is correct way to have electrum added as a co-signer to sparrow coordinator even if it did accept it.

- Bitcoin core gives a single sig derivation path of: 84h/0h/0h (again not the m/48'/0'/'0/2' derivation path sparrow is looking for)

- I believe h is same as ' so in sparrow anywhere there is an h I should substitute it with an '?

- Is this not possible? If it is possible, is it not advisable to do? It seems very few people have tried this and maybe even fewer have software wallets like bitcoin core and electrum as co-signers with sparrow coordinator.

The reason I wanted to do this was to diversify signers and to have some signers that were not hardware wallets. Software wallets would have their own laptop.

Please help! I wanted to at least test/try it to see how I feel about the process, signing, backups, restoring, etc. It sounded nice to me on paper.

Thank you
