You’re welcome. Thanks for the additional info.
Yes, I am suggesting 1 CC mapping, and sending different values of that CC to adjust the mix parameter. For example, a value of 0 will make the mix at 0%, a value of 127 will make the mix at 100%, and a value of around 64 should give you roughy 50%. You should be able to configure your MIDI footswitches to send out these CC values.
