that is tight. Normally, what you can do is appegio the chords in the progression. for ex
if you are doing a 7-3-6 you can appegio the chord off the the 3 to the 6. Also you can do, depends on the style, run the blues scale or minor scale off the three to the 6. It really depends on how you feel as a musician, but remember less is more because if you do all through out in the talk music runs and licks then it can cause a distrubance in the service.
