Before I was aware of the existence of Capablanca Random Chess(CRC), I had
designed my own hybrid of Fischer Random Chess(FRC)(sometimes known as
Chess960) and Capablanca Chess. My hybrid, Capablanca84000, includes 84000
set-ups as opposed to the 21259 for CRC.
The rule differences are:
1. CRC states that the queen and archbishop must be placed on opposite
coloured squares. Since neither piece is colour-bound (unlike the bishops)
I had not chosen to include this rule. Indeed, a common and logical first
move for the archbishop is that of the knight-style jump, thus landing it
on a different coloured square. If it can be proven that the jump is the
more common first move for the archbishop, it would be equally logical to
place the queen and archbishop on same coloured squares.
2. CRC states that each pawn must be covered. FRC does not and neither
does Capablanca84000. If FRC did include this rule, it would no longer
contain 960 set-ups since some contain uncovered pawns. For example,
set-ups which begin with knight-knight-rook starting from either the a- or
h-file contain 2 uncovered pawns on either the a and b files or g and h
files.

To Jeanette and Alina with inquiries dated 2005-05-14 and 2004-12-23
respectively:
There is a good probability that whenever you see an individual with
Capablanca as his or her last name, there is going to be a relationship
with José Raúl Capablanca (1888-1942).
Sergio Gustavo Capablanca (1918-1997) was the son of Bernardo Salvador
Tadeo Capablanca Graupera (1885-1940) and Maria de la Gloria Graupera
Capablanca (1890-1975). Bernardo Salvador, was one of José Raúl's
brothers, the others were Aquiles, Ramiro and Carlos and six sisters,
Aida, Hilda, Graciela, Alicia, Zenaida and Clemencia.
I hope this helps. I am Sergio M. Capablanca, son of Sergio Gustavo
Capablanca and grandnephew of José Raúl.

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:
