[Closed] 27.2mm BrandX/TranzX/One-Up dropper post tinkerers assemble!

Morning all. I'm considering trying to fit one of the aforementioned dropper posts to my old Karate Monkey, however, the standover looks to be just a bit too tight for the 105mm throw.
I've read somewhere that the larger sizes of the One-Up branded versions can have their raised height adjusted for less throw. Assuming that they're all much of a muchness, can it be done to the 27.2mm externally actuated post? Machining spacers isn't a problem, I just don't want to pay out for one and find it's not really viable.
