Sure. I think this is similar to what Paul was saying. But, nonetheless,
if the original poster is interested in experimenting with fixed
intervals over his riff without them staying in the key he can do that
with soundstretch. There is a lot of music out there that doesn't
necessarily follow the rules. I often play parallel chords that don't
necessarily change chord quality according to a given key. It can be fun 
to move the same chord shape up and down the guitar neck. 

In harmony and voice leading class in music school parallel 5th's were
strictly forbidden. But, we wouldn't have the Sex Pistols without them.
