You asking an opinion filled question. Here are my 2cents.
I believe "names" are only of value if they refer to lineage. For example Steve Tyree grew this acro named it Steve Tyrees Whatever Acro(made up name BTW). When i go buy a Whatever acro, it better be from the same colony Steve Tyree has. Other than that i don't care for "names" unless they are in Latin.
So to answer your first question i would call it Valida. A bali tri-color to me is "it came from Bali, and it has three colors". A Bonsai tho i think of G.A.R.F. Bonsai which has lineage. If I bought a Bonsai that that did not come from the folks at G.A.R.F. Then i feel cheated.
Last I would say you have a Valida, a very nice looking Valida. If you want to distinguish it then make you own name up. If it becomes popular and people seek it then people will want to get it from you. It can be as simple as Bela's Vali. If it looks good and other have good luck with it, the coral will speak for itself.
