Mini Keg Idea ??

So I was thinking, I have a small frig that I had stored away and finally got around to digging it out in hopes that I would be able to fit a keg (soda type corny) inside of it. Not going to work tho as this frig has a max of 24 inch inside height to work with. I could fit one 3 gallon in it but not two because of the width and the 3 gallon cost too much. So I was looking around and thinking I could use mini kegs and use this Mini-Keg Tap to connect a CO2 bottle and just use a picnic tap to dispense. I should be able to fit 2 or 3 of these kegs in my small frig and store the others until ready to use. From what I can see I could even force carb in the mini keg if needed. My only big expense would be finding a CO2 bottle and regulator.

Any chance this would work or know of a better way to make this work?

Also I have seen reference to aluminum mini kegs, anyone know who sell them?

Thanks for any help.
