It would be very clunky and would only work for 5 of the FX inserts, but could you set up scenes where the only things which have changed are the assign and/or mix control settings on the FX and scene safe everything else? For each FX insert you’d need a softkey for ON and a softkey for OFF.
Not a particularly good way of doing this really but it’s what I can come up with and it might work
