Troops and Happiness question

[Kamog]

Please correct me if I'm wrong, but my understanding is that the happiness benefit of troops on a planet is based only on the number of troops present. The game doesn't care what components are on the troops or what size they are. So the cheapest way to increase happiness on a planet is to use lots of small troops with no weapons or shields.

This just doesn't make sense to me. It would be better if large troops help improve the happiness more than having the same number of small troops. Is there a way to mod troops such that large troops improve the happiness more than small troops? I took a look at the data files and the answer seems to be no, but I'm not experienced at modding so I'm not sure. Do you know if it's possible? Thanks!
