I have a Shiny nincada which does yield a Shiny Shedinja after evolution. Would you like it? I would really love Shiny Mudkip and Treecko. and yes it is UT. And would you mind if I treated the Shiny Nincada like 2 Shinies since it gives you two Pokemon? If not, I will be more than happy to take the Mudkip.
Also, if youd like, I can give you Wailord, Altaria, Solrock, Crawdaunt, Armaldo, Metagross, Shedinja, Nosepass and Mawile for any of your legendaries that are Shiny. The problem is that I have all of those Pokemon in Pokemon Black which means I would trade them to you via my pokemon black game but would like the Diamond Pokemon to be traded to my diamond version.
