Not sure if it is the same but I linked one I stumbles about earlier in the collecting thread:
About those hobgoblins in scaled down… They are very true-scaly with their human-sized heads, not even very goblin-like, mainly mongols on fantasy beasts. (These are two separate reasons.)
Scaled down you won’t recognize them as greenskins at all.
Maybe something like this would work better?
About the scale: Going from inch to cm will work, but for the scale of the models I’d take something established, either 15 mm (for compatibility with Warmaster, IIRC) or 10 cm (which is frequently seen for minihammer).
Most game systems that are close to GW originals are probably still to cumbersome for the small scale but at least about Kings of War I read that it works well scaled down.
Not sure how much Warmaster differs from WHF, unfortunately never played it, but people say it is one of the better ones.
