Ability for a user to create instructional text which can launch various editor features (images, links, JIRA...)

I'd like to build a template in which the end user can use the richtext editor/wiki markup editor menus to fill out text boxes (e.g. inserting images, creating links etc.).
Currently I'm using

from the Scaffolding Plugin with specified parameters for building text boxes. I know one can use wiki markup to set links oder link to images, but I'd like to use the richtext editor (or at least the buttons for inserting pictures or links) like when you create a new empty page. This would make things easier for less experienced users when they fill out the form.

Context: Confluence 5.1 shipped with instructional text. You can have instructional text which is plaintext and a @user mention. We can extend this to load other things in the editor such as the image, link or JIRA dialogs...
