If you can fit it into the drive's own limited RAM, it should. The 1541
drive is a basically a (user programmable) 6502-based computer of its own.

 In the last 10 years, many C64 guys have suggested the 1541 as
a reader/writer/copier of MSDOS and copy protected disks for the
AppleII...

 I have one in the attic.  Maybe I'll try playing with it some day.

I wasn't advocating using the 1541 (though I have in the past), but simply mentioning that raw GCR storage and interpretation on the PC has been done before. Given the more bare-metal control one has over the Disk-II I would suspect that someone here has the skill to design a USB device to control the Disk-II which streaming the raw GCR back to the PC over USB.
