Hello James,
The original 3warp version of the AxBC would make a good Orion double raider, which does have center warp. The WYN purchased, Orion light raiders (LR), double raiders (DBR), and light cruisers (CR) from the Orions under an agreement that allowed them to have a base of operations, and a shipyard, in the cluster. The AxBC would be a lot bigger than the DBR, being based on a freighter. While the DBR is 2 frigates strapped together. So, don't 86 the 3warp version. Just make it about the size of a WarDestroyer and it'll still be a good design.
