Gogo loco is a replacement locomotion and action controller. It allows you to have better walking, standing and crouching animations and also redoes the way your emotes work so you can add more if you really want.
It's also incredibly overcomplicated and you should just use LocomotionFix instead unless you really want the 3-point cope poses to pretend you're sitting or laying down.
It does not use the FX controller, unless you use the one that also adds a flight collider. So you can just use your own FX controller to do facial expressions if you want.
If you want to use the flight use the avatar tool that the other anon linked to merge it with your own FX controller.
