Being only copilot I can only suggest the idea to captains, but I don't see a problem in overriding GS mini in the conditions that we flew through.
Steady, well established 30kt wind at altitude, gradually and nicely decreasing to a fixed value between 10 - 15kt on ground, I don't see any problem with a Vls+5 approach speed. (VLS+8 actually including the vpilot)
As long as there isn't anything forbidding it in the OM A or B, nobody has a say apart from the captain.
If it can avoid a third go around in less than 6 flights into this particular airport, we will do it.
GS mini does a nice job in harsh turbulence, or light windshear conditions. This was not the case. It was increasing speed for the sake of it, with no added benefit.
Also my reports went through our airline services, they may come back with an answer.
