But one thing is that I receive the response too late, so I have not enough time to contribute to the mailman before the GSoC applying deadline. So can I learn the project deeply and do some extra contribution after the proposal submission deadline?

You can contribute on the mailing list, but it would be unfair to other students to evaluate not your proposal, but other information you send us (and if Google caught us doing that, they would very likely boot us entirely from the program, if not this year, next).

If I have some time I'll take a look at your proposal, but I already have all my time committed to other mentoring, so I will have very little influence on an eventual decision.
