I'm not sure I agree about the lack of support, I hear quite a lot of people very enthusiastic about it. Personally, I think so long as the GFT/Skills test standard of handling, VFR navigation, and airmanship is not dropped, there shouldn't be a problem.
If you want to teach part time only, why not go for a microlight AFI/FI rating? There's no requirement for a CPL, and the course costs about 2/3 of what a light aircraft AFI course costs. Microlight instructors are in short supply, and get paid slightly better than light aircraft instructors (because you can't hour build for an ATPL on a microlight, so they actually have to pay a living wage!).
