Hi Joe.
My own calculations for my invented game of Sac Chess place a 'Missionary' (aka a promoted bishop, in Shogi) as very close to a rook on that game's 10x10 board. On the other hand, what I called a 'Judge' (aka a Centaur, i.e. a piece that's a Knight+General compound, in wikipedia's & many other people's usage) I rate as being worth a pawn better than a rook, in that game's fairly large 10x10 board. So, I'd say either long- or short- range pieces can be roughly in rook class as far as value goes. However, I don't know enough fairy chess piece types yet by heart, in order to name several already invented rook class pieces. Regarding the values of the knight & elephant in Modern Shatranj, for a knight I used the value that the late Dutch player Euwe (former chess world champion) gave (i.e. 3.5 pawns), on chess' 8x8 board (to try to be consistent with my placing a knight at 3 pawns on a 10x10 board). Using his value proved to be a good thing since I believe like you, at least for now, that an elephant is worth a shade less than a knight in Modern Shatranj, and by my own rough methods of calculating estimated piece values for chess-like games, if I set a knight to 3 pawns on an 8x8 board, an Elephant I would work out to then be worth a knight exactly. :)
P.S.: Fwiw, for those interested, on chess' 8x8 board, I'm agreeing with Euwe's having a Rook=5.5 pawns, too, which I also gave it for on Sac Chess' 10x10 board, since for that game I have the short-ranged piece (knight) reduced to 3 pawns in value (in my estimation), at least as a way to take into account that game's slightly bigger board.
