Approach 1:
RTE has got a plugin called InsertVariablePlugin, it pretty much does the same, inserts the dynamic values in RTE content.
2 OOTB RTE configuration examples you can refer to:
- /libs/mcm/components/newsletter/footer/dialog/items/text/rtePlugins/insertvariable/variables
- It is newsletter text component.
- /libs/mcm/components/newsletter/footer/dialog/items/text/rtePlugins/insertvariable/variables/givenName
- It is newsletter footer component.
More on InsertVariablePlugin can be found on widget API page - http://dev.day.com/docs/en/cq/current/widgets-api/index.html
But I guess they refer dynamic values only from logged in users profile so you might need to extend it.

Approach 2:
- We had similar requirement but we did not want to extend InsertVariablePlugin to inject dynamic values. So what we did; while defining content of RTE we inserted dynamic text with placeholders like - $$Dynamic_Val_1$$
- Before rendering the RTE content, we wrote the wrapper function to rewrite the dynamic values with the actual content we need. Basic String replace in java function.
See if any of the approach suits you.
