I had a little time today to enhance the python interface of swftools a bit.
It's now possible to do what you asked for in a short python script:

#----------------------------------------------------------------------
#!/usr/bin/python2.3

import SWF

def fixColor(col):
    if 255 >= col.r >= 250 and 
       160 >= col.g >= 140 and  
       160 >= col.b >= 140:
        return SWF.Color("ff9696", col.alpha) #snap to 255,150,150
    return col

swf = SWF.load("input_file.swf")

for tag in swf.tags:
    if tag.isShape():
        for nr in range(tag.numfillstyles()):
            fs = tag.getfillstyle(nr)
            if fs.isSolid():
                fs.color = fixColor(fs.color)
            tag.setfillstyle(nr, fs)
        for nr in range(tag.numlinestyles()):
            ls = tag.getlinestyle(nr)
            ls.color = fixColor(ls.color)
            tag.setlinestyle(nr, ls)

swf.save("output_file.swf")
#----------------------------------------------------------------------

Of course, that only works for plain color fills, not bitmaps and
stuff.
It's also not colortransform-aware (I doubt that Maja is using
colortransforms, though).
