Wookiee 95% completed needing an idea

[Mikehazard]

Hi im new to this community and have been very impressed with the possitive attitude, just wanted to say that now onto my dilemma i made a wookiee costume a few years ago and it really gets a good response but there is one part of it that really irritates me and its the lack of articulating jaw. i didnt build an underskull for this build the mask is a don post mask with added hair, does anyone have any ideas on a way to make an articulating jaw?

im at ablank as to a workable solution any help will be appreciated here are the pictures i have available to me now i can take more tomorrow

really hard to offer help without seeing a closeup of the mouth.

Likely going to be hard without modifying the original mask (at least some).

I'll get some new pics up today I understand I'll probably have to cut the mouth out and maybe alter the mask in other ways

Sorry for double post but here are the closer pictures if the mouth the latex is already coming apart from the fabric portion and the only part I would say that definitely should stay is the nose

Also when the mask is on the mouth sits right around 3 inches from mine
