Is there a case for shrinking Polybian equites?

[QuintusSertorius]

I play with half-sized Polybian triarii maniples, and I was thinking about the equites. There weren't many of them in a Polybian consular army, just 300 with the rest of the cavalry being Latin and otherwise allied. Given Huge unit size is roughly a 1:10 facsimile of reality, that means they should be 30 in a unit.

As it stands, the unit we have is the same size as all of those allied units, which makes it took big. Now there is a case not to recruit them at all if you've got a young Family Member with your army, since his bodyguard is effectively a group of young equestrians and the like.

So I'm thinking, cut the size of the equites unit by half, or maybe even smaller than that. While they won't be brilliantly useful as a result, in reality they weren't brilliantly useful at all.

Thoughts?
