Question regarding Battle.net name change services

[Zinplx]

When a new account is made for the purpose of shelling & the valued character is transferred to it and then transferred back to the main account in 30 days, you're left with a shell that is merely 1 month old. At what point is it safe / recommended to attempt a Battle.net name change on it? Factoring in that it's only ~1 month old and also very recently had a character transferred to & from via account-to-account. Anyone have personal experience or input? It would be greatly appreciated, ty!
