I've just read the voting thread where everything is detailed. IMHO, if it is to be introduced, it should be as a separate Castle without a level. It becomes too dangerous of an imba; both sides could lose their main hero. And then you either have to level up again, which isn't always possible since all monster chests might be cleared out, or end the game due to the impossibility of continuing.
The unit abilities are terrifying even at a glance: three entanglements + pulls, poison + biting—that's the end for small units.
Fire not working underwater is a disaster for many mages, while water over land is imbalanced. By the way, Meteor Shower is entirely a land spell.
There should be no difference in levels between heroes for descending and ascending; otherwise, one could cheese it. Hit and run.
These are all just rough sketches that might possibly help you refine something.
P.S. Although I voted negatively, such scale cannot but command respect.
P.P.S. GOOD LUCK TO YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!
