Matt, it sounds like you have it already figured out... running the highs instead of lows IS a popular mod, and can easily be done by dremeling (or XACTO knifing) the tiny tab on the high bulb so it will fit in the low socket.
the assembly has a block, and it is aimed lower.
If you are gonna upgrade.. check out the Sylvania silverstars.. run 4 highbeams bulbs with that brand and you're good to go.
