Yeah I'd go with that. Deffinatly a hybrid, looks too smooth for a simple kitbash.
Kinda makes me wonder what other hybrids would be worth seeing. I've always thought an Excelsior/Intrepid hybrid would be attractive.
That's why I always liked the Enterprise C as it was a real smooth transition between TOS movie ships and the Galaxy class. The Soveriegn was great but it was a bit of a jump from the Galaxy, (sort of made the Galaxy look a bit outdated).
