Yes - Phil Brown at Caving Supplies in Buxton used to sell exactly that. I don't know if he still does since the Pantin came out though.

This works reasonably well, but there's a bit more torque on the right ankle than if you use a foot harness and Croll suspended just above the right foot, which is the current standard practice. In most cases using a Pantin in a Frog system requires only putting half your body weight on the Pantin foot with each stroke, whereas with a ropewalker you are placing 100% of your weight on that foot with each alternating step. Either approach works for ropewalking, but I think the Croll/foot harness/double-bungee system is more comfortable on longer pitches.
I've had problems with clothing getting sucked into the small brass pulley used for the double-bungee, and this has been solved by the pinch protector sold by On Rope 1. The pulley sits inside this nylon housing and keeps things running smoothly. I would recommend trying this rather than deal with two separate bungees.

I have been advised by those more knowledgeable than I that it's important to connect the double-bungee pulley directly in the middle of the chest plate. Rigging it to one side or other will cause it to bind.

That is a definite myth.
I opt for the frogging croll on my D ring when rope walking.

That is a definite myth. I ALWAYS attach my pully to the far left slot of the rock exotica roller that I use and it never binds. I do this because of my croll (frogging) that is attached to my D ring.
I used to do the double pully method, but found it a waste due to achieving the same results with placing the pully to the far left. This keeps it away from the croll gate and the bungees never get sucked into the gate with the rope. I also use the smallest bungee available without dropping down to the really tiny stuff that has the white tracers. You don't need 1/4" thick bungee or larger to make it work.
What WILL cause it to bind is poor posture, slouching and slumping. You have to keep your back straight when climbing so your bungees are under load during every inch of possible movement. Slouching (poor posture) causes slack in the bungees and they wont work, and it will obviously cause issues. This is one reason why I opt for the frogging croll on my D ring when rope walking. Inevitably when you cross a bad lip, bungees lose tension and its very hard to climb because of this. Using the second croll allows me to "frog" over lips with little hesitation.

Good to know. It was told to me by someone that should know, and I didn't question the advice.I opt for the frogging croll on my D ring when rope walking.
I've heard you mention this many times before and never took the time to figure out what you were talking about. Lately I've been having difficulty getting linked images to open with either Explorer or Chrome (but that's for another thread). From the thumbnail image it looks like you don't have a lot of room for your left knee ascender to move up before it contacts your Croll. Maybe your style is to take lots of short quick steps, but this might be a limitation for some. I like the idea of being able to dispense with the ascender above the chest roller, but with the relatively high steps I usually take I'm pretty certain a Croll would be in the way.
