         IMO, you probably need something like this:

1) Preserve all source colorspaces  (eg. no conversions of any type!)
2) Convert to Default CMYK Editing Space
3) Convert to untagged CMYK, preserving CMYK numbers
4) Prompt

         Same as above, except RGB instead of CMYK and no need for option 3.

         Actually, #1 would be a (most likely) non-PDF/X compliant 
PDF, but with support for all possible colorspaces.

         #2 would be PDF/X-3.
         #3 would be PDF/X-1a
