Does anyone have 'instructions' on how to construct this?
Take one Igloo 70qt. MaxCold Roller cooler.
Place 5-gallon corny keg on lid.
Trace diameter of keg on lid.
Cut out traced circle with jigsaw.
Clean up/enlarge hole with file.
Enjoy your new keg cooler.That being said, I have found that opening the lid (with corny in place) to fill the cooler with ice is inconvenient because the keg keeps the lid from opening more than a few inches (which is the reason I started this thread.) It is clear that for maximum ice filling ease and convenience, the lid must come off with the keg still in place. One could simple cut off the plastic hinge pins that the lid rides on, but then the lid needs to be secured somehow, so that once the cooler is filled with ice and the lid back in place, it won't flip open or ride up while the cooler is being moved. One could simply use bungee cords or rope or even some sort of latches on either side of the cooler/lid to keep the two pieces together. But to me, that would sort of cheapen the whole thing and reduce it's coolness factor, something I personally want to avoid.
I think what I am going to do is drill out the hinge pins and the hinge bracket so the there is a hole running from one side of the hinge to the the other. Then I will run a stainless quick-release pin like this

through the hole or two (one from either side, if I can't find a single one long enough) to replace the hinge pins. This will allow me to easily remove the lid for ice filling and keep the lid secure once filled without any unsightly cord or devices mounted to the outside of the cooler.
Although honestly- I suspect the lid will fit securely enough without any hinge mechanism at all to stay in place throughout normal usage.
