We guitarists often tend to use, or even overuse arpeggios in solos. It's hard to name several of your guitar heroes who don't do it, also. Actually, they're the ones who popularized it, which is awesome! Arpeggio technique on electric guitar is one of my favorites, and for that exact reason I began searching for possibilites of incuding them in rhythm parts.
It's good to get around in all sorts of genres, and in your favorite you have to be the best as you can. Using arpeggios in playing rhythm parts might help you stand out a bit, and explore additional ways to spice up your music. I definitely advise that you first take some of your favorite rhythm parts and rearrange them so they have arpeggio fills, without loosing the vibe or feel of the music. Then, explore some totally different music genres and learn how to do it there. That will reflect on perception of your music domain in extremely positive way.
