If you want shorter feedbacks than 64 samples within a patch, there is no way around reducing block size. You may be able to optimize by putting only the very necessary (for the feedback loop) objects into the re-blocked subpatch.
Then there are some classes that do internal sample-size feedbacks, like [rpole~] or [fexpr~]. While [fexpr~] is quite flexible, it may be even more expensive than a subpatch with blocksize=1 (at least that's what I remember when I compared two implementations, but this observation might have been specific to that kind of problem).
