No.

I am sorry but you always seem to find band aids to your set up and how
you deal with live patches internally. While I can see that something like
a hybrid mode might be useful to people if done right (and we are not
there yet), the combination of it with bpf overrides or anything like that
is not something I would like to see in upstream.
