Need Help with Camp Stove

Hello all,
I am relatively new to this forum but not exactly new to camping and the outdoors. I was a Boy Scout twenty years ago and I'm looking to build a chuck box like we used to have back in the Scout troop. One side of the chuck box folded down and held our propane camp stoves. I am looking to use the materials I have available to do something similar with a slight improvement and I am hoping to draw on this forum's considerable wealth of knowledge to make it work.
Essentially, I have two of those inexpensive propane camp stoves that you connect up to the little one pound bottles and I'd like to disassemble them and build a four burner cook top similar to this:
The camp stoves I have look like this:

I bought them at Wal-Mart because I was pressed for time and needed a solution. I probably have about as much into both of them as one would a basic model Coleman brand propane camp stove. These little grills work to a point. I think each burner is something like 10,000btu which is plenty to make coffee and fry eggs. The Achilles Heel with these little grills seems to be the regulator attachment that connects the grill to the source of propane. Both of them crapped out rendering each grill useless.
The regulators look something like this:
Is it possible to disassemble both the camp stoves I already have, attach some sort of new regulator that would also connect to a bottle tree on a 25lb propane bottle as shown below and cobble together a new cook top?

I'm a relatively handy guy and I have lots of tools. What I do not possess is a good knowledge of plumbing fitting and what I can thread or solder together - which is why I'm asking for help.
In looking at the stove, it seems to be a pretty simple device:
Two burners

Soldered to this connector which connects to the regulator shown above:


What I would hope to do is bypass the cheapy regulator with something more reliable. Also, I am trying to figure out if these lines would be soft or hard soldered together and what types of fittings I would need to pull this off.
This whole thing may sound like a fool's errand and perhaps it is. From my perspective however, both the camp stoves are junk right now because they have no regulators and I can't use them. If however I could spend a few bucks on a couple fittings and turn lemons into lemonade, I'd consider this worthwhile. Have any of you tried anything like this before and does anyone know if/how this might work?
Thanks!
Jason
