Merging Flash and Toon Boom Files

I have only one copy of TB, so I’m having some friends help me paint my frame by frame bits in Flash. I export an swf from TB, they open it in Flash, paint, then export a new swf, which I then take and edit back into my main TB project.

We haven’t started in on this full force - I’ll have about 2 or 3 ‘inkers’ working this way. Is there anything that we should be aware if before we start? I know file naming will be critical, and we’ve already established a templates Flash project that will maintain frame rate and image size.

Thanks for the help!
