I was thinking of a combination of:
1. Bajorian Assault Vessal
2. Bajorian Solar Sail ship
In that, the hull should be the brassy gold color of the solar ship and the hull's skin should reflect the texture of the solar sails. That would just be for looks.
3. Future starfleet ships:
We have seen future ships like the Aeon and Wells. They are more compact and no saucer sections. Also, the current Prometheus ship is more streamline.
This first Bajorian/Federation ship should reflect the transition from saucer section styled starfleet vessels to the more compact vessels of the future. Also it would go with the tradtion of compact vessels that the Bajorians are used to.
So...no saucer. It's would be too "traditional" starfleet.
