That works for me! What do you have that you can trade?
Correct me if I'm wrong, because I wasn't on Serebii for a while and didn't keep up with the goings-on as much as I normally do, but I don't think Zekrom can be shiny unless there was an event that I missed.
I have these Pokemon right now for trade:
Safari Ball- Houndour, Aron, Smeargle
Fast Ball- Elekid
Level Ball-Sentret, Pidgey
Moon Ball-Psyduck, Horsea, Gligar, Zubat
Heavy Ball- Makuhita
Love Ball- Swablu, Vulpix
Lure Ball- Psyduck, Buizel
Friend Ball- Oddish
Dream Ball- Misdreavous, Tirtouga
You can catch a shiny Zekrom in the ORAS.
