Wowwww those are awesome...I would say your idea is not only possible but is a reality for ARs. Check it out: EM3-556: 30 Round Easy Mag I have several of these and they are very easy to load and are reliable. These mags are heavier than the standard mag though so you may strain yourself picking them up to load. I doubt we will ever see this type of product for handguns though.
Ruger MKII mags use a miniscule follower button and a heavy duty railroad car spring to power the follower.I have heard there is a device to make loading these mags. easier.Anybody know of this device?

A spent .22 brass can be used to help push the button down as well. It wont act like a lever, but if you stick it on the top you get a larger thumb contact area to push with. (yeah, I'll have to take a picture someday)
