Hi,
Respect 
it sounds great, but I have more questions, I will try to answer them by using the FMs . let us to see .
It is really interesting,
we have also to create a method to look if this method already exists, or not, and there are many open questions.,
we can do many thing during run time, or you can do a Customizing table, which parameters you need, ..
what should be done, and it will be created. this sounds good.
in Customizing table, it could be done, for example, active as flag ( method) active or not,
delete, create, etc.
Regards
Ibr
