Personally, I like the Black OPs/Special OPs idea (for a different Island such as Isla Matanceros) but it would need alot of substance. I say borrow some ideas from the games and novels, and mix it in with the film's past.
Let's say the film takes place 25 years later after the incident on Isla Nublar, mysterious and gruesome deaths have been reported and covered up by world government officials (United Nations) along with InGen in a coastal city located in Costa Rica. A joint operation is set in motion, a group of special forces is sent to the nearest island off the coast of Costa Rica (Isla Matanceros) to investigate/eliminate the 'threat'.
The team is attacked before arriving (several die in the process) and the survivors wash ashore without communication, and 70% of their equipment/hardware/weapons. Upon searching for a way off the island, they travel deep into the island (losing several more comrades along the way) and seek an abandoned military base and compound (which belonged to InGen). Here, the unit uncover a sinister plot with the last remaining Dinos and the DX disease.
