I also did this to an old set of MT62 cranks. I always thought even 165mm cranks looked a bit long for the missus who's 167cm short. And when we moved away from track cranks on her bikes I couldn't find any decent double or triple cranks in 165mm or shorter (actually I could but a) I didn't fancy them b) they were too pricey and c) I had a good stockpile of 175mm cranks).
I wouldn't use the term milled but the process involved a drill press, pedal taps, angle grinder and some files. Now she has custom 155mm MT62 cranks and her rotation looks much better. She told me it was a bit weird at first but got used to it after just a few km's. She can't really hammer down like she used to on 170mm cranks when she's out of the saddle but otherwise she's completely sold on the idea of shorter cranks for shorter people. A bit like smaller frames, handlebars, wheels etc.
Oh it's the Mulo I posted on the previous page. I don't seem to able to quote myself but there are two pics.
But basically I chopped off the wishbone and dropouts and replaced them with a pair of S-bend seatstays and Konga dropouts. Also moved around some braze-ons.
Exploding (recalled) Shimano R515's paired to R550 levers.
This same combo was previously fitted to my tandem and worked much better than the MT200 hydro's that are fitted now. Not super snappy but heaps of leverage and power.
