The best to do is not change anything inside CH grip, because buttons/HAT are wired in matrix scheme with required diodes already installed.

Usually CH Figherstick follow this scheme:

What is need is connect the wires in Arduino and set the corresponding matrix in MMjoySetup.

You can do different, using Shift Register circuit, what need 5 wires for communication of grip whit controller o base, but this require replace the CH PCB under HAT (desolder, solder), with new created for this new wiring method, a complicated and laborious process.
Anyway for this approach look in Rel4y upgrades in DCS forum: https://forums.eagle.ru/showthread.php?p=4310926#post4310926
