I don't even own a DAW, I'm just a troll.
I don't have Spaces. I fiddled with a few reverbs I do have, and haven't yet found a setting that gets into the ballpark of Lyndhurst Hall. Yes, a few of the concert hall reverbs I've tried out sound very nice with the library on its own.
Spaces II is really good! But (this might sound weird) all I've used on SStWW is RC 48 on the bus, and believe it or not the concert hall sounds pretty damn good!
I mean, it's not the freakishly excellent Altiverb or Pro-R, but it definitely works well in a pinch imo.
