security: is it possible to separate the blockchain and wallet functions?

I'm looking for a way to use bitcoin-core in monero-way (use blockchain daemon and wallet daemon separately).

I would like to run the bitcoin-qt interface on my laptop and connect to an external node with full blockchain. This way I can share my entire node with other people and my wallet will be safe.

Is it possible to use bitcoin-core in this way?

P.S .: I hear about electrum-server, but I don't want to use other software.
