Welcome to the boards. Your question contains too many variables. Hate to say it, but you're going to need the services of a specialist, such as an engineer to calculate loads. There will be a lot more required than just extending joists. Don't even attempt such a change without professional help, otherwise you could have a situtatiion that happened in Chicago awhile back with it collapsing and killing a few people.
