`lnd` on Raspberry pi zeros? Did somebody try to run the bitcoind full node on the Raspberry pi 3 and one or more lnd nodes on one or more Raspberry pi zeros?

My goal is to support multiple LN clients without having to run a full node for each client. Raspberry pi zeros are cheap, storage and bandwidth are not.
One node to rule them all and in the darkness bind them

Run a Raspiblitz (EUR120)

Then run slave devices on ESP32 (EUR5)

121 would need to be ported with macroons
