I was chatting to a CCP dev at EDU 2019, and mentioned the idea of faction titan-specific doomsdays - in particular, a corpse-powered DD specific for use on the Molok, which already has a corpse bay after all. I mean, who wouldn’t want to hose down enemy capitals with a death-ray powered by the finely minced bodies of your defeated foes? It is a ridiculous idea, but stay with me.
Allow the molok to fit a direct Doomsday (say, the Exsanguinator, with a blood red beam, and a slightly liquid/splattery graphics effect) that starts from a base 1.1 million damage (10% damage increase on the Judgement), but firing it uses 100 corpses from the corpse hold (for example). You could extend these faction-specific mods to other faction caps as well.
The Chemosh could use a blood raider’s siege mod, with improved armour repair bonuses. The only catch being it uses 25 corpses per cycle to get the increased performance.
The Dagon could have a blood raider remote armour repper that uses corpses to improve performance.
In a similar vein, the Komodo could have a doomsday that consumes fighters from its existing fighter hangar to increase damage, refitting them to kamikaze into the target, borrowing True Sacrifice concept from the Shadow (different faction, I know)
In theory, every faction cap could have a thematic faction-specific mod that would provide enhanced performance, and consume an appropriate “fuel”. At worst, you will have FC’s telling entire fleets to self-destruct their pods on the undock so some lucky soul can harvest all the meat popsicles for the alliance leadership’s molok, while at best you will have frigates burning around a major battlefield scavenging corpses to keep the DD firing!
It will also give more reason to see some of the faction caps on the field (where they can be popped 
), and create a new niche industry for corpse harvesters.
Plus, it will be funny
