Hmm, havent really seen anything on microtonal scales, but after googling in most cases the normal scale is retained and only adding frets onto board shouldn't be too hard to fit . You could make it easier if you order a normal scale slotted neck without frets and cutting new slots for additional and then fretting (no existing frets to get in way. )
Working out which EDO you want to use is the only consideration. EDO (12 Tone Equally Divided Octave) on standard guitar, centre of scale is 12th fret and on picture looks as that would be 17 EDO ie centre of scale is 17th. On your picture the added frets are just splitting the existing fret spacings.
