The Chancellor has R+N powers and the Archbishop has B+N powers (thus not colourbound on a square or rectangular board), just as Queen has R+B powers (again not colourbound) and thus it could be argued there is no need of having minimally more than one of any of these in a given square or rectangular board variant's setup. Also, there is Ben's reasoning.
In the case of my 10x10 Sac Chess variant, I found it useful to have a pair of (for each) Archbishops and Chancellors simply because I wanted to fill up exactly 30 cells per side in the setup, to make each side's camp full (i.e. have no empty cells). I also used several other pairs of arguably classic compound pieces, such as Amazons, partly for this reason, and partly to cope with the 12 classic piece types in total I chose to include per side in the setup.
