Sorry to dig up a thread from the dead but I'm crossing the same bridge here, planning to use Sierra-1's for L/C/R and need to make the rear channels of the 7.1 system disappear since it's a family room and there is just no place to put any boxed speaker... (20x20 family room in a new construction)
The wife must be appeased by sacrifice and will only be appeased by allowing the walls of the house to consume 4 rear speakers.
So here I am. I'm looking to do the 'best I can' to timbre match the rears to the L/C/R Sierra-1's though I know it may not be perfect. I'm primarily listen to the mains for 2-channel music, so the rears (in ceiling) should server primarily as surrounds/special effects for HT.
In an effort to timbre match and in the research I've done, it seems the biggest deal should be to match the tweeter type as closely as possible. Doing that and looking for the 'best reviewed' in-ceilings with matching tweeter types (just described as 'soft dome'). I 'think' I've narrowed the selection down to Noble Fidelity's L-85 or more specifically their L-85 LCRS which is the same speaker in a 15* directional mount.

I can audition these as they offer a similar plan to Dave's, try them and if you don't like them send them back. But I guess I'm just looking for input on if I'm going about attempting to get the closest timbre match possible the right way. I'm no pro at this...
So Dave... when are the Sierra-1 in-ceilings coming out?
I'd consider the Sonance as well, but quickly got lost amongst so many product lines/models on their website. Is there a particular model that timbre matches the Sierra-1's well and performs admirably enough to match them together without shame?
