I believe I have already responded to very similar general request of yours:

In the thread I'm linking above, I also suggested that such
implementation will have to be proposed as an extension.
That is, for at least these reasons:

1. Parallel implementation must not replace existing GIL algorithms
    but should be proposed as complementary features.
2. GIL core library must not require OpenMP.
3. GIL extensions can require OpenMP.

I likely will repeat myself, but I'd suggest you to start with reading:
1. https://github.com/boostorg/gil/blob/develop/README.md
2. https://github.com/boostorg/gil/blob/develop/CONTRIBUTING.md
and links from those two documents.

Then, start designing, experimenting, prototyping, etc.
i.e. the usual software craftsmanship applies.

If you have any specific questions, if something doesn't build,
if you get stuck, then post your questions here or boost-gil
as recommended here:
https://github.com/boostorg/gil/blob/develop/README.md#community

> And also do you all think this is a good enough proposal?

This is not a proposal, but just an idea tossed into the air.

Please, read the GSoC guides to learn how to write a proposal
https://google.github.io/gsocguides/student/

I'd also point at this article which every student interested in GSoC
should read, IMHO:
https://github.com/boostorg/boost/wiki/Google-Summer-of-Code%3A-Advice-From-Former-Student-Louis-Dionne

You are also welcome to implement your idea and submit to GIL
as a new feature via Pull Request (PR) before even GSoC starts.
Every Boost library accepts PRs proposing new features.

I don't understand what kind of compatibility you mean.
Perhaps you should read these
https://www.boost.org/users/faq.html
https://www.boost.org/development/requirements.html
and see if anything there addresses your concern.
