I worked with a customer about 2 years ago on a process similar using ProFlow head to put paste in holes for through hole... Similar to Pin in Paste. Somewhat successful; but ran into heat related damage issue from TH components through reflow.

I won't say never but very rarely do we have problems with the flux seperating. The way we get around the 1-2 hour warmup time is this: The day before we run a particular job, the last person takes out the paste needed from the fridge as the last t
