Hello. I recently thought of a cool idea for an add-on. Basically, you can create a Application-Forum, in which you can setup an application form, so when people go to that forum, and Instead of it saying "Post" it says "Apply." People then, can click the apply button, and fill out the form you defined, then Click another Apply button to post the application, which then posts in the forum. You can define whether people can view the forum or not, and all that stuff using the normal xenforo permissions.
