Could we have a series after DS9 a few years later that is set 20 years after the war or something? Or even take Abrams idea of starting a new timeline inside Enterprise and that's why we have the Xindi war.
I am afraid I have to disagree here with you. In theory you are right. The way the Andorians were set up was exactly how it should be done in a prequel, but (and this is a big but) earth made first contact with the Andorians within 10 years of the founding of the federation and at first they were relatively hostile towards the Andorians*. I simply can not believe earth would form a federation and basicly form a new country 10 years later in such a situation. In my opinion a big mistake of the Enterprise is that they tried to explote two different eras in star trek history. The first are the early explorations of earth in which they meet the people who would become their friends and allies later on. The second is the years that would lead to the Romulan war and the funding of the federation. At this point they would already know the Vulcans, Andorians and Tellarites. but you could still make first contact with species that would become important later, like Bolians, Betazed, Klingons and of course Romulans.[Enterprise] should be about meeting all the classic friends and enemies for the first time. Almost everything they did with the Andorians was spot on....
What killed the franchise was not the TV series, it was the movies. ST Insurrection and Nemesis killed the franchise.
The problem with Star Trek was in my opinion that with the exception of DS9, they tried to recreate TNG with a poorer cast and writing. Voyager and Enterprise should have kept their premise of a respectively a strip with two factions stranded 75 years from home and a prequel series with a lower technology. Instead they played it safe and recreated TNG.

Or rather better, a series set on a new colony, which is not exactly fighting for survival each day, but has its set of issues and goes further into a "Picket Fences"-area, exploring life in the federation when NOT on a spaceship.
ACtually I do seem to remember having read somewhere (and I might be wrong, mind) that the colony approach was once in consideration for what became Voyager but discarded because so soon after DS9 no one wanted a static location.
