to fit the mini heat shield you would have to either fabricate some strap type mounts or grind of some of the ceramic coating and repaint the small area (which will be behind the mini shields) around where you get the threaded lugs welded on with a heat proof exhaust paint or get them ceramic coated again, personally I plan on getting some Stainless Steel hose clamps and weld lugs on to them, Also I have not got any issues with using my Highway pegs only time I have scorched my jeans was while in heavy Sydney traffic while using rear brake my jeans happen to come in contact with rear pipe which is where the mini heat shield would be.
I have an 08 Std with the Std Footboards conversion which put the feet in a similar position to Std pegs about 1 1/2 inch higher than a Classic or Touring the other area you will need a heat shield is down back where you muffler pipe connects to Header , as a few can testifie this area likes to melt wet weather pants.
the first picture is before and second is my prototype solution which does work, just doesn't look good enough
