Dude I actually do try this
Over a AG shel in the left hand play one two or three or all four of these triads as a run and let the last one voice lead into the Dminor
E major
Db major
Bb major
G major
if you dont like the sound of all the chords or the whole triad you can use one or two notes from the triad
YOu can also play a Aalt chord
A/G C C$ F
and over this chord you can run these notes
A Bb C Db Eb F G A
I dont know a lot of runs but you do know you can always precede a chord by its diminished below and dominant or major sevent above
