Kinematics config/dependencies

I keep getting flak for asking these things, but regardless;

I would like to use RatOS, but always struggled with the interconnected web of dependencies in the config.
My printer is a custom coreXY IDEX, but starting from a Vcore4 idex config.

I'd like to not have the axis inverted as the ratos_hybrid_corexy, which is what I had running by setting up klipper manually before, it worked, but was lacking the bells and whistles of all the nice macro work in ratos.

I get errors if I try to replace the kinematic callout, and I get errors if I try to change the inverted from true to false.

Any tips on figuring out how to avoid these would be really appreciated
