Acheron, Styx, Despoiler (BFG:R) and even the Repulsive (upgraded) are all abeam, defensive aspect, ships. The Hades requires some form of head on approach. I would make a couple of Carnages out of your cruisers to use in the defensive aspect along with the bulk of your ships. You could proxy these as Murders in a couple of games to try them out with your Hades, see how you like that. As for your other 2, well Devs and Slaughters are both great ships but both work better in pairs, more so the Slaughters. So I would make them with 1 lance deck each and leave the other deck free. That way you could bluetac in launch bays for Devs or WBs for Slaughters as the occasion demands.
