piece values

In chess, the values of each piece has been mostly worked out (within a small variation) ... eg a Queen is worth 9 or 10 pawns, and a knight worth 3 pawns etc ... any thoughts on what values to assign arimaa pieces?
 
I know that pieces change in value as more material in exchanged, but that is the same in chess, and also differen't positional characteristics suit different pieces in chess (eg a knight does better than a bishop in a closed position, but in an open position it's the other way around).  I suppose I'm talking about an average value.
 
I'm thinking that an E is worth more than 2 cats and a dog??

One of the more thorough discussions on this subject is the thread "(no) absolute score values for pieces?" in the bot development forum.

If you had to use static piece values I would suggest R=1, C=1.5, D=2, H=3, M=5, E=10, even though the other thread points out a bunch of reasons it is a bad idea to use static piece values.  Specifically, an elephant is worth way more than two cats and a dog in the opening, but in a endgame of ERR  vs. DCCRR, the side with more pieces has a big advantage, all else being equal.  I'd be interested to hear your ideas on the material in that other thread.
