Don't do that. Take the color photos, open them up in Photoshop, dump the color channels:
Open a curves layer, switch to the A channel, and click on the lower left "dot" (this is your greenest of green), and set the Output to 0. Do the same in the upper right corner (this is your magenta of. . .uhm magenta) and set the output to 0. Switch to the B channel and do the same. Boom, all color drained from the photo (which is, to me, more pleasing then a simple desaturated or RBG Channel Mixed image). Then pop over to the L channel, and adjust your L-curve as you see fit (since you are only adjusting the brightness levels of the photograph, it better handles transitions between blacks/whites). Profit.
Oops. I tried doing what you said, and the photo just came out all black. it was like the brightness had gone from it.
