Mod requests (orders). Auto-translated

Hello. I would like to implement the idea of elite squads without the involvement of an enemy hero.
The idea: on the map, there is a regular group of mixed mobs, which includes a leader stack that has a higher level than the rest of the units in the squad (Example: a squad of 100 skeleton warriors, 100 skeleton archers, and 40 archliches (leader)).
The point of the mod is that the battle ends in victory after the leader is killed, not the entire stack. Is it possible to implement this in the game without combat scripts? Because if it's done through scripts, it would involve giving the main hero the ability to track all the leader mobs I use on the map (and the map is large), which would mean that not only the squads in the desired battle would be tracked, but all of them – this is not an option, the map would be too large. How do I see it? When creating a mixed stack, add a specially trained checkbox that will indicate the "leader" of the squad, after which the battle will automatically end in victory.

Colleagues, can you tell me if there are mods similar to the Harmony mod at /post/1125663/ that change the appearance of the skill wheel and add new skills and abilities to it? Approximately how much would it cost to create such a mod?
The author of the aforementioned mod started developing it but unfortunately couldn't finish it.

I want to implement 3 tiers of Tier-1 creatures, that is, an upgrade for elder gremlins and pest gremlins. But I need high-quality recolored textures. Unfortunately, I don't have the talent to do it beautifully. Perhaps there will be an enthusiast who wants to try recoloring them?
