Chances of getting more Valhalla content?

Valhalla being a rougelike leaves so much room to add and innovate. Even if it's not frequent, updates here and there that add more Greek enemies, boss fights, challenge rooms, upgrades, etc would make it even better and add more replayability and variety to the mode. I would very happily pay for it too. Would like to know what else you guys want to see added in Valhalla.
