I think that there is definitely room for more, given the popularity of the license, and Jurassic World: Dominion coming out next year. Maybe a ten inch velociraptor to start? Also we do require a regular Spinosaur, and an Indominus Rex at the least.
I am also extremely surprised we have had at least 3 pop keychains from the line, but no set of minis as of yet, I believe minis would sell very well.
