...I am podering if is a worth to merge Rhino jar or if is better to create
another implementation with Groovy.... or both?:-D...
Why not both, but for me the priority is clearly to solve the Rhino merge/license/whatever issues. As much as I'm a fan of Groovy, Rhino *works* today, and rather well.
So if you can pursue your Rhino merge project, all the better!
