Yes of course this would do the job.

I am working on a product, which should make transclusions possible in 
plone without hacking the plone/zope code. For this it should be 
possible to add a transclusion rule (perhaps similar to wiki style 
{{USER:CONTENT}}) in text fields. The first idea was to add a special 
validator for this to check correct syntax. Because it should be 
possible for every text fields in every content type, the use of 
standard validators would be the easiest way.
