I heard somewhere that before they decided on Avery Brooks as the star for DS9, two of the actors considered for the role were Anthony Head ( BUFFY THE VAMPIRE SLAYER) and Jonathan Pryce ( the High Sparrow on GAME OF THRONES). Maybe at that point they were thinking in terms of an elegant Britisher like Patrick Stewart, then decided that it would be too similar to ST:NG.

Unfortunately I don't remember where I heard it. Has anybody else heard about this?
