Update....
I had a similar derailleur collecting dust so I decided to shorten it even shorter to see if I could get more clearance, Clarence.
And now I have 2.5" ground clearance (on gears 3 and 4) or just above the rim.
Now I can have a full flat and no pulley touchie!

I could post pics but it's just like the last one but... ya know.. more.

Might go for another 1/4" with a different idea but at this point it's not needed, it's just to see if I can.

455% gear range... not bad....
