It's a good start, I'd guess. You'll get discontinuities on the block boundaries. You probably want to insert that part of your patch into a overlapping block scheme with windowing, to reduce clicks/noise.
However, I bet there's a simpler solution that works almost as well with an all-pass filter (or the hilbert~ abstraction) and a mixer.

Yes, I thought about windowing and overlapping after I posted. But I don't know the simpler solution you're mentioning...some example how to set it up?

Multiply the left outlet of hilbert~ with a cos(theta), multiply the right outlet with sin(theta) and add them together. That should approximate shifting the phase by theta radians. Sorry I can't provide a patch or anything.

No worries, clear enough. I'll give it a try.
