I know what you mean as I already have such a component with pluggable block store and networking.
While you are at it you could aim for isolation of bitcoin specific decisions and algos from generic block chain code.

The magnitude of refactoring you would have to do to get there from main.cpp and the rest of the hairball
is harder than a re-write from scratch, and the result will not be impressive, just hopefully working.
I think a slim API server was a lower hanging fruit in Core’s case.

BTW, support for refactoring is an example where you see if your tool set is modern.
