Easy.
@monkeypatch
class Cls:

And then you define monkeypatch as a function that locates the prior
class, augments it, and returns it.
If you actually want this, it's only about a dozen lines of code. The
trouble is, it's nearly impossible to generalize which things should
be lifted in and which shouldn't, so it basically has to be written
for each use-case.
