Not an art but more of a rule set-look up sanda/sanshou.
To second this, San Shou (and it's more dangerous cousin, Lei Tai) is probably the best example of a competition format built to accommodate the throwing styles many different arts. Judo, jujutsu, Shuai Jiao, wrestling etc.
It's not uncommon to find all sorts of different competitors, from MMA to Muay Thai to traditional CMA/FMA, take part in it. The format allows basically any modern throw, including stuff that's been banned in other formats like Judo and Muay Thai. Basically, if it puts the other dude on the ground, it's legal. In the Lei Tai format, the ground is at least a few feet below the platform, and there are no ropes.
Cung Le's book on San Shou is fan-tastic. He came from a Vietnamese kung fu background and was able to successfully transition through San Shou to the pro MMA circuits.
Josh Schafer is someone I really like, he teaches Mantis, Tai Chi Chuan, and is a PT, but has a great background in competition San Shou throwing. And I think he has two PhDs in medical stuff. He often gives seminars to different TMA schools. Typical Canadian, always giving.
