MacBook – Can a 2015 Macbook Air MagSafe 2 connector be filed down to work with a 2009 Macbook Pro

The title pretty much says it all. I ordered a MagSafe 2 power adapter before realizing my MacBook Pro uses the Original MagSafe. After looking at both connectors, it appears the MagSafe 2 connector would fit the MagSafe power port if it were filed down on the edges a bit. However, I'm concerned the power delivery would not match what the computer can handle, and I don't really want to go through returning and buying a new power adapter. Likewise, I wouldn't want to destroy both the adapter and the computer at one go. Does anyone know the specs – whether these two are "electrically compatible?"

I just filed down my new Apple MagSafe power cord on each end and it totally works with my 2012 15" MacBook Pro.. Just found out the edges and I did a few passes over the top were the pins are and pow! It totally works
