If you want a better Gamling I suggest this torso with dark gray or dark red arms and Eomer legs:
The newer viking and castle themes got a fair amount of good random rohan people torsos
Btw in that post I was talking about the helmet only, but yes I think the same thing about the torso.
+ I understand you want to repurpose the extra eomers you got, I would recomend mixing up the helmets tho, the rohan solder are quite ragtag
