That's a great idea Rick. I'm going to try that one as well.

Another good stretching exercise is to play a standard rock & roll lick in A on the two bass strings. Index finger on the E string fifth fret, middle finger on the A string seventh fret. Then, while holding and playing that pair, add the little finger on the A string ninth fret and then on the tenth fret.

When you can do that easily in A, slide the whole thing down to Ab, then to G, etc. See how low you can go and still make the 6 fret stretch.
