I'm surprised you see a reduction in scanner noise in *color* negative
highlights using multiexposure scans.  I usually find that if I set
the overall scanner exposure correctly the entire dynamic range of the
color negative is well within the scanner's range and nowhere near the
scanner's Dmax.  Some B&W negs and slides do benefit from this
technique.  I use Photomatix's combine exposures feature to blend
bracketed scans (and DSLR shots).  I like it better than HDR and
tonemapping.
