I have not heard the two speakers next to each other for several years, but what I remember is that while the midrange quality and timbre was mainly similar for the two (same drivers), the Linnbrook had more bloom and fullness - this could be because of the lower FR perhaps, not to mention dual speakers.
I would suspect a 50 Hz crossover point would be OK for the Taylo, though hard to tell without knowing how far you would put the speakers into the room, room size, crossover slope, etc etc. I do know that the 'posted spec' on the Linbrooks is very accurate in my experience and measuring - perhaps the Taylo is as well.
As for tweeters, what you are describing is the SEAS not the Scanspeak - the millenium is the smoother tweeter.
Last, as everyone always says, ask Ty - he knows his product better than us and is always helpful.
