Have you tried Enigma? Sure I read somewhere they would do repairs or adding bits to titanium frames but not 100% sure.
Although a lot of the Ti frames are produced elsewhere (although some are still produced in house I think), they do the finishing in house. Brazing on cable stops etc. So worth getting in contact.
