If you use pipewire instead of pulse audio then you can install pipewire-jack and then use any of the jack patchbay applications to rewire the channels. Currently I use qpwgraph but there are several options.
I got a glass bed then and simply put’ it on the stock bed. Takes 5 degrees more heat and a little longer to heat up but I am very happy with it. Btw, when you are at it: I would isolate the bottom side of the bed to conserve energy. You can buy ready made isolations with a glue- and an aluminium side.
