I'm not sure how accurate this may be, but from what I can remember of GT when I used to play it back in 1.5, there might be a singular option that flips it all over in the GT config file. Something like easymode=true/false, that generally changes the taste of the mod, so fiddling around in there yourself for a little bit may be easier than trying to rip the configs from another pack.
Although, as indicate, it's been a really long time since I've played GT, so this may have changed, or I may just be misremembering.
