In spite of what I see as the drawbacks of this variant (unprotected pawn for each side in setup, rectangular board [though allowing smothered and back rank mates still], bishops clearly stronger than knights, the fact the chancellors might be developed symmetrically and traded in short order sometimes), this was a good try historically to cut down on draws and opening theory.

On this particular variant's board dimensions of 10x8, as compared to 8x8, IMHO the archbishops would seem to come closer in value to chancellors (though not queens), though I personally have lingering doubts about archbishops being quite as good by comparison on 8x8 or 10x10 boards, any computer studies aside. IMHO, the bishop component of an archbishop would seem to have a number of extra potential good squares near the centre (or in range of the enemy camp) on a 10x8 board, without the rook component of a chancellor benefitting as much as often in return (unlike would be the case on a 10x10 board). On a 10x8 board the knight component of an archbishop would seem to have a number of extra potential good squares near the centre (or the enemy camp) for local scope, balancing the benefit received by the rook component of a queen on such an empty larger board than 8x8.

My tentative estimates for the piece values in this variant would be: P=1; N=3.5 approx.; B=3.75; R=5.5; A=8.25; C=10; Q=10.25 and the fighting value of the K=3.2 (though it naturally cannot be traded).

edit: Here's a 10x8 CV that uses 2 powerful and unusual pieces, besides the chess army and Berolina pawns:
