One of the things I have been doing lately to break out of ruts is to figure out keyboard parts and solos on the guitar. Most guitarist will figure out sax and violin parts but I like the way keyboard players have a certain way of playing different sequences.
A couple you should check out are:
In The Cage - Genesis. Tony Banks keyboard solo uses a lot of cool scale lines and pedal tones.
Firth Of The Firth - Genesis - I have been working on the main piano intro. Lot of arpeggios the move all over the guitar.
Cinema Show - Genesis - The end keyboard work is awesome. Lots of stuff to practice sweep picking with.
Roundabout - Yes and Rick Wakeman - Cool arpeggios that have some big stretches.
Just a couple of examples so check them out.
