Heroes V - Remake "File restructuring, 'junk' cleanup, and game optimization"

The mod is very good. I have an idea. About 8 years ago, a mod was posted here where Death Knights replaced Undead, etc. But at the same time, the Undead themselves (or rather, their models) replaced Ghosts, Spirits, etc. They are just too beautiful to be discarded as neutral creatures. At the same time, they became larger creatures, and to balance this, Liches were made smaller; they also look like they occupy only one cell on the battlefield. I would like to see something like this in your mod.
