Yes, but not as simply as swapping the bulb. There was someone posting both here and on LFPF and making very nice replacement Omega D lamphouses using careful color matched LEDs. I bought one and love it. Evennness is at least equal to what I get with a 211 or 212, VC response to filters seems the same, there is virtually no heat and no worries about negative popping and the lamp life is rated at something like 30k or 35k hours. Brightness is just about evenly in between a 75W 211 and a 150W 212, which is fine for my work. See the thread here:

This may not help you much for what you want to do, granted. You could always just try it. Worst that happens is that it doesn't work well and you waste a few sheets of paper testing.
