If you roll off the mains (some don't, including myself) your main amps will see less of a load, thus you could do with smaller amps.
I see no issue with rolling off your mains, so long as the xover is well designed/made, and the xover point is suitable. If running one sub I generally prefer a much lower xover point, say around 40Hz (I run dual subs at around this point). Also, I would not remove your amp and buy a 25% lesser powered amp based on this fact, as the actual volume required doesn't directly equate to watts generated. So maybe now you can get away with a 90 WPC amp...?
Now the reverse of that, is you've removed the bass, which is the most demanding on the amp.
Do you already have a 100W tube amp? If so, and you're happy with the match/sound, I wouldn't rush out to get a smaller amp. Just me maybe...
