Answer 1

You can do this with git submodule or subtree, I use submodule for this kind of reason.

https://git-scm.com/docs/git-submodule

example :

/mainrepository
/mainrepository/subrepository

cd /mainrepository/subrepository;
git init .
cd ../
git submodule add ./subrepository

then open seperate remote repository in bit bucket then 
cd into ./subrepository
git remote add origin https://bitbucket.com/path/to/subrepository.git

basically it is all about that.

I have no detailed information about subtrees what I know, it is more advanced than submodules. But if your needs are basically matches with submodules it is easy to maintain.
