I will chime in only because I am a fellow horn lover, have heard the Duo's a couple times (not the Trios) and own SM-60Fs for my HT system.
Somewhere I saw a link where you could simulate the pattern control that you wanted. Were you looking to use the center 90 wide and 60 tall, or flipped? I'd likely go 90 wide as that pattern would suit more rooms and minimize floor and ceiling (more ceiling if you are placing on floor) bounce. If you find the link you might want to play around as a narrower pattern might not be a bad thing in your room to minimize side wall reflections.
Can it keep up with Avantgarde speakers? Yes, most definitely. They won't dig as deep as your system as a whole, but at least as deep as the Trio without subs as the large horn IIRC has a cutoff somewhere around 100+hz.
I would have opted for the SH50s if my room were bigger, but the SM60Fs fit my space and room size better. Looks like you have the same space constraint.
What are you running your Trios on, amplification wise?
I have no idea if the Trios and the Synergies would match well synergy wise, I'd guess that it would be close enough for HT content. Everytime I heard the Duo's we were running them on SET amps and I've never run the SM60s on SETs. You could always use a bit of EQ to match tonality if necessary.
I've heard of a few folks who sold big Avantgarde speakers to buy the SH50s after hearing them, so I don't think you will be disappointed in their performance. The constant directivity of a Synergy together with the superb coherency of of the design makes it a perfect center channel.
