This ship would make more sense if it was what Voyager looked like at the end of Caretaker. Also, Janeway and Chakotay should have had a fight to the death to decide who would be Captain. They would kill each other and Seska would be Captain.
Never cared much for this ship class (although of course, your rendering is impeccable as always!) To me it doesn't show enough differentiation from the basic Intrepid design to warrant a unique shipyard setup; if it was a thrown-together-fast-design-to-stand-against-the-Borg sort of thing, seems like they would keep churning out bigger numbers of fewer designs, rather than spread construction resources over a lot of "kitbashes".
That to me was always the biggest flaw in TNG/DS9/VOY era Trek (well apart from the awful Voyager writing), the designers never really thought through what the organization of the fleet should be and created ships to fill roles; instead they just through stuff together to give the impression of a diverse and very big Starfleet. (Star Trek Online is even worse with the variants, but it's off in its own pocket universe.)
