This is a pretty common situation.

Please do not re-invent the wheel.
Use the standard SPL approach instead. This is working fine on a
number of other systems already, so it makes zero sense to invent a
new, incompatible solution.
I don't see much chances for your new approach to ever go into
mainline.
Best regards,
