I run a full node on my Raspberry Pi at home. I want a desktop wallet that uses this full node. Not interested in using remote-x or xpra or setting up an electrum server.
I'm trying to understand what you mean - do you mean you want your Raspberry Pi to hold all of your blockchain data and your main desktop wallet connect to it (similar to your electrum server you mentioned)?
Maybe explain some more of your use cases and we can provide more information.
