Is it possible to make the same unit can recruite in differnt unit size ?

[deemarksu]

I have an idea to change unit size to 250 . But there 's problem in seigeing battle that I can't put unit on the wall ( I think AI can't too ) . So If I make an single unit can recruite in 2 unit size like this .

Example :

Armored Sergeants 250 men --> To used in field battle or seigeing settlement . ( more prize,upkeep and less replenish rate )

Armored Sergeants 150 men --> To used in defence settlement . ( less prize,upkeep and more replenish rate )

Is this possible ? If it possible How can I do that ?

You would need to make 2 units. Give one a different name in EDU/EDB, though you can have them both be called the same in game by entering them as such in the units' text entries.

I think the only solution to the problem is to change the settlement models.
