JRA,
If you have licenced copies of both the Abe Workflow Server and Adobe Form Server then yes what you are asking is possible.
In order to create the PDF w\ Form\Data merged, you will have to call "Agent.createPDF(sData, sTemplate, bIsDynamic)" within a script task in Workflow Designer. ( This assumes that FS is installed on the same Server as Agent ). The online help should explain the function params in detail.
Once you have the PDF you can build a custom mailmsg, passing a fully qualified email address within the Mail.To method, and attach the file as required.
