You mean https://www.spice-space.org/multiple-clients.html ?

Even if you tweak that, you would be receiving data from all
displays, I think.

It wasn't design with this kind of usage in mind

You could have a client to connect on the host and having this
client to split the data to all rpi instead. You could even
consider playing with video walls, splitting one 4k display in 4
full-hd ones, etc.

Nothing like this is implemented but lots of work is already done
by GStreamer, in case you want to play with it.

Cheers,
