Re-Edit:
Okay. So the more I think about it, the more I think that this would be a neat faction to see revived. I can see the transport divisions of RS funding a private war with the Unioners. In addition to those gimmicky shotgun setups I mentioned, Tigersharks with Stealthblades seem like they would be quite effective. You could also mix Flammenwerfer-C1's with Kusarian Cleansers for a nice mix of 5.88 and 3.03/6.67.
Security assets could also make good use of the AP line, which inRP is easy to obtain (Pay money and sign on a dotted line). Hammerheads have 7(O_o) slots to mount codes, and are just as agile as Wraiths (while perhaps being more fair to use in pvp, since you can actually hit a Hammerhead). If that's not your style, there's always the Bottlenose or Orca for those who are into gunboats (Rheinland missiles on an Orca might be scary), though I would be careful in bringing a Solaris Bottlenose into a snub-fight.
