Nick, you would have to set up a multi, assigning what kits you wanted, what other instrument sounds you wanted, and then turn off program change RX on the XS. Then save it.

You could set up user patches on the s900 with the CC0 and CC32 set to correctly transmit the patch changes to the XS, and then save these into a style, but I reckon it is much easier to set up multis on the XS.

Just my view.

It is a bit fiddly at the start, but once the multis are there you are right to go.

You could sort of set up your own band combo on the XS, just assign the channels according to the style output channels on the S900.. BUT with Program RX set to off.

I have about 12 different multis (for different genres) setup for when I want to use the pattern generation of the PA but use the great basses, guitars and drums of the MoES.
