I really like this concept, though I haven't played it before. Concerning the sample 'Case II', it is worth noting that even if U captures R--freeing B--W can immediately recapture B by the same move suggested. (It might be worthwhile to capture B now (as in the suggestion) just to threaten U's current square (if R is ever captured at his starting square, that is).
Rooks do have the devastating ability to win the game in four moves (after two moves getting into position) by sweeping through the opponent's home row if they can avoid being captured first. While bishops enjoy greater mobility, their range is only half the board, so I think the pieces are relatively well balanced.
