Hazbin Hotel. Because of spider-related reasons. Come on, there are tons of lewds out there, and the show is practically begging for it. Lots of LGBT and kinky potential. You could even get the furries attention and money for it, and that's profitable.
And on a different note... Das Boot. Seriously, many men in their prime in a closed space and under a lot of pressure. Stressed, terrified, miles away from female comfort, who start relying on their peers, and suddenly finding out his fellow Hans looks cute under a certain light...
Ok, maybe I'm the only one asking for this second one, but the former would have tons of fans.
