How to allow Double Posts for Original Poster only

[yukirina]

Using 4.2.2. Currently using integrated double post merging feature from vBulletin, but I wish to make it so that the original poster of that thread can double post while all the replies cannot. Is this possible?

Bump for visibility.

There is nothing available ATM, but if I get some time, I can look into it.
