I wrote a very short summary of
getting Forkcoins out of multisig, part of this can be used without multisig too.
For splitting Forkcoins and forcing replay protection,
I can get you some Forkcoin dust. However, before doing this,
I'd love to get $1 worth of pre-fork coins that exist on all 3 chains (BCH/BSV/BCH-A). This can only be created from unsplit coins, which you have. I'm not sure if Electrum adds a locktime, and if it does it might influence replaying transactions. This is one of the things I'd like to test when I have a small amount of unsplit coins.
Note: before doing anything related to Forkcoins: move your Bitcoins to a new wallet so you don't risk them.
