Somebody already mentioned that FILA is working to incorporate Pankration under its auspices and promote it, but they didn't give links.
This is the link to the FILA website that deals with Pankration and grappling:
FILA Grappling
Basically, FILA is promoting 3 levels of competition:
Grappling

FILA Grappling)
Grappling is a non-striking hybrid sport formed of wrestling, jiu jitsu, sambo, and many other submission fighting styles which consists in applying submission holds and choking techniques in order to make the opponent abandon the fight.
When including grappling into its field of activities, FILA had the vision to unite the grappling community under standard international rules and offer a generic discipline that would go beyond the specificities of each submission fighting discipline. Straight forward and easy to understand rules were thus created to facilitate the participation of athletes coming from different fighting backgrounds in international competitions.
Pankration
(
FILA Grappling)
Pankration, from the Greek words "Pan" and "Kratos" meaning "the one who controls everything", is a world heritage martial art with the unique distinction of being the only martial sport in existence today that can legitimately trace its roots to the ancient Olympic Games from 648 BC to 393 AD. Today, pankration is developed by FILA as a mild form of Mixed Martial Arts (MMA).
When including pankration into its field of activities, FILA had the vision to encourage the perpetuation of this ancient form of total combat from which all forms of modern Mixed Martial Arts (MMA) descend. If in ancient times very few limitations were put upon the discipline,
today's pankration is thoroughly regulated and can be practiced as a mild and safe introduction to MMA. The head not being a target and the additional protection brought by the uniform make pankration an ideal omni-directional martial art for all.
Combat Grappling
(
FILA Grappling)
Combat grappling is a form of safe amateur Mixed Martial Arts (MMA) that incorporates techniques from most existing Martial Arts systems, creating a unique fighting environment that alternatively takes the fight from standing to ground positions. Combat grappling matches are either won by grappling holds such as joint locks and chokes, or by striking and kicking techniques.
Combat grappling was created by FILA to fulfill the need for a properly managed and regulated form of amateur Mixed Martial Arts (MMA). Through the mandatory use of protection gear and limited impact rules (especially regarding ground and pound), FILA intends to offer a sport that can safely prepare an athlete for a professional MMA career or provide extended knowledge on realistic fighting scenarios.
Combat grappling is practiced with board shorts and an optional rashguard along with approved protection gear that includes head gear, shin protectors, and gloves that allow grabbing and holding the opponent for a comfortable application of grappling techniques.
Having a respected global body like FILA trying to support and promote amatuer MMA is great news for the MMA community in general. As another poster rightly pointed out, in order for the Professional circuit to grow there needs to be an extensive amatuer circuit and FILA is looking to do this. Heck, with its support we may even one day see Pankration or Combat Grappling in the Olympics.
