I found this awhile ago (probably from this here forum). Does this help you out?

work in the 59.94 project:

1) In the 23.976 project, select all the clips you’d like to use, and export them as QT reference files with the setting “Same as Source”.

2) Close your 23.976 project, launch the 59.94 project, and import all the QT refs you just exported. The Avid will pad out 24p clips with 2:3 pulldown to create 59.94 media. This is how “24p over 60p” works, so the footage looks exactly the same. There’s no quality loss (that I’ve been able to discern), as it’s merely duplicating frames and copying them to another media file. There shouldn’t be any decompression/recompression going on. The QT reference is simply an intermediary file.
