There is no issue, Cliffy used the pins of the LUX GPin to Heron GPin, because he wanted to have silver plated pins, but the pins of Heron are different from the ones of X/v3 due to 201 connection.
Perhaps it would make sense to make a Heron Lux GPin - the base would need to stay SS because of the contact with the metal in the Heron base, but the collar and the pin could be silver coated. Or perhaps just the collar and pin can be sold separately - it does seem like a waste to order a Lux GPin to use only a half of it for the Heron. I would be down for at least 4 of either one of the above configurations
Not a fan of cleaning the brass GPin pieces with Nevr-Dull - already replaced all my V3 switch screws with the silver coated ones.
I think that there would be many other takers if something like this is made, if it makes sense and is not a hassle for the GP team.
