Yes, this is a good starting point.

I don't think this is a good idea. Why not start with the executors
included in Boost.Thread library (develop/master branches)

The executors directory included already some executors. One of them the
basic_thread_pool is a good starting point. The work-stealing
thread_pool could be based on it and the implementation provided in
CCIA 9.1.5.

I would need to know more about your background. Are you familiar with
thread-safe lock based data-structures? lock-free data structures?

Your first proposal should be as complete as possible and you will need
to probe that you are knowledgeable of the problem domain, of Boost
environment and of C++11.
Showing a prototype of a thread pool having specific queue for each
thread (See CCIA 9.1.4) that make use of the sync_queue in Boost.Thread
would be really nice.

Which compiler(s) are you using? Which platform(s)?
Do you use already Boost?
