Submaster HTP merging with live values

Hi,

I have a couple of lights receiving live values occasionally, via OSC. In order to maintain a minimum brightness I would like to have a submaster set a minimum intensity which the lights never drop below. I thought this would be easy, set a submaster to HTP-merge, map it to the (intensity of) those lights. Boom, done.. But nope, can't make it work.
Either the submaster has such a high priority that it always overwrites the live values, even if these are higher and after principle of HTP should set the value. Or the live values always overwrite the submaster, no matter what.

I've played around with intensity master, varyious priority settings and other submaster settings, but no avail.
(Weirdly, with Mode set to Inhibitive, I can set up a fader/submaster to be a limiter. That's easy.)

Is it even possible?
