Hypothetical, as in a crazy Situation in an AU DxD where Rosswiesse never became Rias' rook.

Ravel would make a great queen but  high class devils like her really only uses demonice powers to fight,  since we haven't seen her fight we can asuume that she fights like a high class devil. So the queen piece is a bit wasted on her as only 1/3 of the benifits of the piece are used.

Rossweisse however as proven to be good with both the Bishop piece anf (After training) the rokk piece a welll. Also she has prior experience supporting a iditotic king (Odin).

Also with the trading thing i read a story of Issei a third year and A  high class devil and it made me think. What if it was posible to trade pieece of one type to get a servent of another type. For example, if Issei wanted to get Kuroka into his peerage along with Ravel and Asia as well he could trade 6 pawns for her (2 Bishops= 6 Pawns) or he could trade a mutation paen that  was equvilante to 6 pawns. What do yous think about this theroy?
