a few small ideas
The opponents could dismantle the conquered buildings after a certain time to strengthen themselves while expanding (armoured worms, armoured nests).

Partially build near the conquered part.

Example
In the case of gigantic solar cell blocks or similar constructs, the attackers could turn the entire cell block into a gigantic armoured nest hive if they are not careful.

The artillery can be converted (if the mod is active) into the worm artillery.

ein paar kleine Ideen
Die Gegner könnten doch die Eroberten Gebäude nach gewisser zeit demontieren um sich selber zu stärken beim Expandieren ( Gepanzerte Würmer, Gepanzerte Nester)

Teilweise in der Nähe von dem Eroberten part erstellen.

Beispiel
Bei Gigantischen Solarzellenblöcken oder Ähnlichen Konstrukten, könnten somit die Angreifer den gesamten Zellenblock in ein Gigantischen gepanzerten Nest Hive umwandeln wenn man nicht aufpasst

Die Artillery können die ( sofern der Mod Aktiv ) ist in die Wurm Artillery umwandeln

It's possible, I'll think about tomorrow.
Probably, it'll be a nice pair with another mod(s)

Hm, maybe it would be a good pair with https://mods.factorio.com/mod/humanoids2
I created a new topic there: https://mods.factorio.com/mod/humanoids2/discussion/611582f02a8e7438a3fe83b9

Also, there's https://mods.factorio.com/mod/erm_redarmy
https://mods.factorio.com/mod/erm_redarmy/discussion/61164046ae83c00729b42f34

Also, https://mods.factorio.com/mod/Hive_Mind but my thoughts are vague with it right now. It seems to need "reform conceptually" for the mod.
It's like, biters kill you for resources. "Reverse idea" of https://mods.factorio.com/mod/biters-for-resources

(armoured worms, armoured nests)

So, you want https://mods.factorio.com/mod/ArmouredBiters and https://mods.factorio.com/mod/worm-artillery for this mod, right?

Also, https://mods.factorio.com/mod/Kombat_Drones can extend varieties for some of those mods /\
Damn, I want an EMP tower.
