This is a mod I worked out originally almost 2 years ago(minus the FET and divider correction in 7135 drivers with higher voltages and yes it requires some caps and jumpers. Here is a pic of how that mod was done. It ran 3 XML’s in series from 12V input. I ended up just stacking the caps on the pins of the regulator. This was before I knew of the MTG (before Gen1) and I never used it because of the lack of low voltage detection. It’s kind of exciting to finally be almost in position to use this idea after so long. 
Edit-oops! Here’s a pic with the regulator in place sans caps. It appealed to me because of the sot89 package. 
At the time I was also toying with better heat sinking for 7135’s.
