I have a similar concern with the Pegasi as with the Nereids; the familiar Pegasus is [N?R]. (Again, you may be using these as non-capturing Carriers, in which case take the same note as weith Ships.)
Even aside from the specific concerns about the Nereids and Pegasi, it's generally simpler to have only two, or perhaps four, of any given piece type, other than those functioning as Pawns. (Don't take that as gospel, of course; I violate that guideline plenty!)
I was planning to use Pegasus as the "Sky Horse" in order to neutralize the power of some extremely powerful pieces. Their number will help achieve just that.
