Very unlikely they'd use that code directly - would likely be easier to re-implement the features wanted natively in the blender codebase...
On top of that, there were always suspicions that some of the Shake codebase didn't come from perfectly 'legal' origins from an IP perspective in the early days (its API was very similar to something Alias was working on at the time, and became Maya). I've heard rumours that was a reason the people responsible for Shake were never considered for SciTech awards.
