I managed it, so it's definitely possible. From memory, I put all the F6 floppy files into a hard drive folder, then installed them and ignored all the dire warnings, then rebooted and went into the BIOS and change to AHCI before going into Windows. That's the important bit or you'll get a BSD.
If you ghost image first then you can always get back to where you are now if it goes wrong. My XP is still working fine 6 months later even though it's now part of a dual boot setup with Win7.
