I think it should be ok, just still concerned about the clowns in a 14g but other than that it looks like a reasonable list.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
Turbos would be fine I have 20 in my 220 reef and 12 in my 125 FOWLR if they knock over your coral you obviously are not affixing it right.
As for the clowns a mated pair will do fine.
That stock will work if you do weekly water changes.
IMO 2 clowns will be stressed out unless they are already a pair and don't get divorced. Remember clowns are very messy eaters so the bio load would be heavier than it would be with 2 fish the same size. Clowns do fight and the male will need to be able to get away from the female.
