(Personally, I'd want to change the Chinese Pawns to Guardians or Anti-Pawns, but that's just me.)
That would make them too powerful.
Seriously??? Guardians are no more powerful than Stewards, any more than (actual) Berolina Pawns are more powerful than orthodox Pawns. (And that's an "apples-to-apples" comparison, since the Guardian is basically a Berolina Steward.) Anti-Pawns would actually make them less powerful, since they'd have no forward or sideways move.
