Theoretical question: converting AR-15 mags to mini-14?

Hey guys...long time lurker, first time poster. I'm waiting to see if I won my online auction for a Mini-14 RR, and was pondering the magazine question. A few threads back, someone mentioned a 'do-it-all' magazine that worked in both the AR-15 and mini-14. As would be expected, this after-market magazine was a pile-of-you-know-what, but it got me thinking - how hard would it be to convert AR-15 mags to fit the mini-14 magwell? Would it be something simple like grinding down the side-latch on the AR-15 mag and adding a plate on the back so the mini could latch on to it?

Anybody ever try this? Like the title says, it's just a theoretical question - I'm okay with buying a few PMI/Thermolds and calling it good, but how hard would it really be to modify the AR-15 mag to function in a mini-14?

I think you'd have to remove to much material from the front of the Mini 14 reciever for the AR magazine to fit. With that much material removed up where the bolt locks I think you'd be looking at reciever failure because there won't be enough material left to support the bolt when it locked. The Ramline combo mags your talking about that fit the AR15,AR18,and Mini14 are narrow in front like a Mini 14 magazine.
