I asked Johnie King if he had run into workable solutions that came from his customers?
One thought he shared was split cases using padded gig bags like those used for keyboards.
Here's what I'm trying...
The original hard case weighs 22lbs.
This keyboard case is reasonably padded and fits well. Total weight in the case is 27.1 lbs.
This tripod carry bag weighs 13.1 lbs. and easily fits the leg bag and the pedal bar. It has a shoulder strap that makes carrying it much easier.

To be sure, this stuff isn't designed for extended road trips or airline. But, to load this onto the bed of an SUV and carry to the stage, I think it will be just fine.
I may add some foam stiffeners depending on how much these stretch after use.
If anyone is interested, these cases came from Amazon - under $100 for both.
PM me if you'd like the links.
