V. Cool, I wouldn't label it as a 'refit' when it's clearly got no relation to the Akula bar the 2-vertical-nacelles arrangement. I really loved these Designs based off the Excelsior that aren't obvious kitbashes, they're actually
different ships with the same aesthetic, kinda like different models of car made built by the same manufacturer.
Q: Wasn't this one of the Ships of the Starfleet ships by Todd Guenther back in the '80's? He did specs for a really cool looking SCS called the Ingram based of the Excelsior, similar to this. Worth checking out.
