I have a really good idea: instead of going forward with the proposal in the OP, reboot the entire T2 battleship lineup.

First, CCP should take the work that they've done on the proposed Marauders (the fancy new animations, siege-module-but-not concept, etc), ditch the MJD bonus and all pretenses of PvP usefulness, add a small damage bonus, further-reduce their mobility (make them handle more like a little capital ship than a battleship) and rename the ships "Vanguards" or something and play up the fact that they were designed specifically for destroying pirate encampments or whatever in their description. Go hog-wild and make the ultimate PvE battleship, while trading off qualities that would render them useful for PvP (mobility, buffer tank, ability to receive remote reps, etc) in exchange. Pick a specialization for this T2 hull and stick to it.

Then, having actually created a specialized T2 BS hull for PvE, take the Marauder class title, take re-skins of the formerly-tier 3 battleships, and make a class that's actually useful for PvP in hostile space. Make these ships similar to what blackops battleships are currently, but without the jump portal generators and with an obvious combat focus instead of the hodgepodge of attributes that current blops bs have:
