Supporting a new platform requires a lot work. It would be more reasonable for you to first try to get a good support of the master branch before start thinking how to support Python versions.

Python 2.7 in 2018? Really? Tick tock:

http://python3statement.org/

Usually, we don't support new platforms in CPython without strong support of a core developer. See the PEP 11 for more conditions like buildbot requirement. I suggest you to start working on a fork of CPython and maintain your changes in a branch. Git rebase makes it easy.
