Ideas similiar to this are floating around for quite a while now.
In the meantime there is a pretty clear proposal on how to implement
this. You may want to research about GEGL for more information.

I am not familiar with GEGL but I think dynamically adding new effect
layers was on the list of stuff that should be possible.

It definitely needs a new infrastructure - and there are lots of other
reasons to exchange the current infrastructure. GEGL is supposed to
solve the other problems as well.
