Reprohuset,
That would probably work. However, note that having us develop custom php scripting will require you to purchase professional services, it is not a free solution.
If you want to look at this on your own, there are many php files in the "templates" directory of PSW. Open the one that corresponds to the skin you're using, and then you can try playing with the php files. Note, however, that in the other directories of PSW, many of the .php scripts are encrypted and cannot be modified. If modifications to these files are needed, you'll have no choice but to purchase professional services.
Regards,
