Adam Nitti shared a concept of playing the 2nd and the 5th when improvising over a minor chord.
For example, instead of playing a C minor pentatonic scale over a C minor chord, you can also play the D minor and G minor pentatonic scale over the C minor chord.
Check out his video below for further explanation:
Another thought came to me is to use the F major Pentatonic (which is the same notes as D minor pentatonic) and the Bb Major Pentatonic (which is the same notes as G minor pentatonic).
Have fun!
