Oh no, please not.
I'd rather see them to make actual Klingon ships like the K'Vort or a t5 K'tinga then just ANOTHER ugly Fan-design.
Even the usual Klingon-fan designs turn out to look much more awfull then the (mostly already prety ugly) Federation ones, and seeing that what won the Fed-contest instead of the at least bearable designs... nonono. No Klingon contest like that......
I'm all for a KDF ship that is fan designed and is the KDF equivalent of the Enterprise F.
And really, after they made the Kar'Fi, I think we're well past the stage of worrying about what it will look like.
