Can't say I recommend this for fancy rims, i.e. at your own risk and convenience, but something similar happened to an Open Pro of mine, with raised bits of rim causing brake noise/wear. I used a nice sharp chisel to plane off the raised parts -- hard steel easily sliced the aluminium. I rested the flat bottom of the chisel completely flush on the still flat part of the rim. Worked pretty nicely...
