Lots of info here on visa runs to Mae Sai.

My question: is it possible to do a visa run (for 15 cross border crossing) to the Mae Hong Song area?

Thanks for your input and help.

No, but Mae Sot is an option.

And a good thing too because MHS immigration makes up their own rules.

There is no official border crossing point near mae Hong Song

I think there is an official border crossing, but its only open to Thais and Burmese at the moment. If that changes its only about 200 Klicks to Taunggyi
