I used a slight variant for that setting this past weekend on a borrowed Nord Electro73 which has a fantastic B3 emulation.

For the kind of music we were doing (straight up 3 chord, sometimes 4 chord rock and reggae), I used lots of

888008008,
888000000,
888008000
and
000008008 on a couple tracks as a little background whistle-pad kind of a thing.

As you can see, I was there for the growl!

There's a 2-track, off-the-board mix I have on CD but haven't listened to it. I'll pick out the non-embarrassing parts and perhaps post some snippets if I get permission from the band leader.
