Hover Point at 75 % collective with symmetrical head setup

Hi!
I’m currently doing my head setup with a symmetrical pitch range of ±12 deg. I know it’s not really necessary to have -12 deg with a helicopter used with Pixhawk in a UAV operation. Nevertheless I’d really like to keep the symmetrical setup, because I fly all my other helicopters like that and it’s a way to feel where I actually am in the pitch range. So in any flight condition I can feel where the collective stick is and I instantly know what the helicopter is doing.

Now my problem is that the helicopter hovers at approx. 75 % of the collective pitch range. (Of course not at mid stick, because that’s 0 deg.) Switching to an automated flight mode (or back) would probably lead to a very rough transition. So my question is, if there is a way to move the deadzone of the stick from mid stick up to 75 %.

I looked at the THR_MID parameter, but as far as I understand that’s the exact opposite thing which helps me to move the hover point to mid stick. Am I right?

A workaround would be to program a pitch curve in my transmitter that puts out 50 % when my stick is actually at 75 %. But that doesn’t seem to be a very elegant way to me. Do you have any ideas?
