Richard,
Here is some information I have on the value of the Carrera pieces which I came up with when designing my own Carrera-esque opening setup:
Here is a table of four different derived values for the pieces, obtained
from three different chess variant playing computer programs and one other source.
Piece
ChessV
SMIRF
Zillions
Aberg

Marshall

The ChessV numbers were obtained by looking at the source code for ChessV.
The SMIRF values, derived by Reinhard Scharnagl for his SMIRF chess
computer program, were obtained from
this web page.
The Zillions of Games' values were obtained by looking at the values of
pieces by right-clicking on them after loading a fresh Schoolbook zrf file,
and before moving any pieces. Aberg's figures come from right here on the variants server.
All four agree on the following:
A bishop is about a half-pawn more valuable than a knight.
Two knights are worth more than a rook.
An archbishop is worth more than two knights.
A marshall is worth more than an archbishop.
A queen is worth more than a marshall.
Two rooks are worth more than a queen.
A marshall is worth more than a rook and knight.
A marshall is worth more than two bishops.
A rook and knight are worth more than an archbishop.
The verdict is still out on some other exchanges:
A rook and bishop vs. a queen.
A rook and bishop vs. a marshall.
A bishop and knight vs. an archbishop.
Two bishops vs. an archbishop (Two bishops are probably worth more).
