I've not played with the FTB launcher yet, so this is theoretical. Adding it to the Technic Launcher wasn't all that hard.
Generally, you need to follow the 'manual' install version of the liteloader install. Find the version.json that is used by the launcher and add the liteloader magic to the forge magic already there.
Id google FTB liteloader and see what's out there.
Stupid, I should have tried that first before bothering you. Works fine now, but I'd still opt to drop liteloader if possible...
Either way, thanks!
