XF 1.5 Possible to start contact form overlay from a post?

[Triops]

I would like to use the Xenforo contact form for a competition in my forums, where everybody wanting to participate shell send an email via contact form.

Is it possible to initiate the contact form as overlay from a thread? The normal link opens it as page, but overlay would be more nice.
Smallest solution for this, please?

Or is there an addon which creates a button in a post which could be used?

I think the only real option would be to create a BB code that does exactly this (basically it just outputs the HTML you want).

Otherwise, it would require some sort of add-on (such as allowing HTML in posts, but that's always questionable in my eyes).
