Converting the profile ^before^ 8bit RGB will avoid some artifacts of
the profile-to-profile conversion process.

Bruce does provide an example for editting 1st in ProPhotoRGB before
converting to 8bit. There is every advantage for editting with
highbits in either wide or narrow gamuts ...

Understandable ... but understand you can't go backwards from 8bit to
highbit, nor narrow gamut to wide. Therefore, for the purpose of
"archiving" all your image information, you should reconsider
archiving your scans in highbit. You never know when you'll want to
retrieve the original scan and do a sever adjustment to it.
Note that Photoshop 6 makes it very easy to work with an "archived"
wide gamut image while also working with a "working" narrower gamut
image. Both images will be displayed in their own color space ... and
if your monitor calibration is right on, you'll not be able to "see"
any difference between the two. You can be confident you can be
working with ^all^ your image information.
