Trying to get to the meat of your questions here... I just did the exact same switch that you did (25.5" to 27", Carvin -> Agile).
Are bends harder?
Really, "harder" isn't the right word. It's different for sure. For the same string gauge and tuning, you will need to bend the string farther to get the same change in pitch. Down-tuning will help this. Lighter gauge strings will help this. A fixed bridge will also help this. But really, you'll get used to it. Don't worry about it so much.
Are pinched harmonics harder?
Again, not harder, just different. Partially due to the fact that they are located slightly differently than the 25.5" scale guitar, and also due to the change in tone (pickups), and also the change in hand position.
The safest bet is to somehow get behind a 27" scale and try it first. I didn't have that luxury, but took the plunge anyways and am LOVING it. Of course, my testimonial may not be the same as yours if you decide to do the same thing.
I can definitely vouch for the Agile guitar that I got though - this thing is amazing.
