[@Shiny Keldeo] So a couple of recommendations, first I like the old ship and such. However it is going to be outclassed by most modern ships so it will probably fall into more of a carrier or frigate role rather than Destroyer. If you want a more up to date model of ship, the Republic did build the Endurance type Star Destroyer which is heavily based off the Venator.

Secondly all Republic fighters have been brought up to standard and even the Resistance doesn't use T-65's. Look more towards K-wings, E-wing's, and the X-wing T-85's. B-wings are still used as well but they are aging, Z-95's would be suicide with the even faster TIE's, T-70's generally were sold to pay for new T-85's.
