Plugin to create virtual posts and/or pages?

Is there an existing plug-in that will enable me to create posts and/or pages on the fly, incorporating standard content plus custom content drawn from a database (picking up the custom content based on a shortcode in the URL)?

For example, if I provide someone with a link to mydomain.com/version247, is there a plug-in that will then display:

Standard paragraph paragraph paragraph

Standard paragraph paragraph paragraph

(Customcontent247 displayed, drawn from the database)

Standard paragraph paragraph paragraph

Standard paragraph paragraph paragraph

etc?

Any advice greatly appreciated.
