Alternative numbered notation

Hello! I would like to know whether it is feasible license-wise in Musescore to amend either the source code or to write a plugin that makes the software use only numbered notation (and one which is customized by me) instead of the standard music notation. That is, standard music notation would disappear completely and would be replaced by a sort of only numbered notation.

The thing is I like quite a lot Musescore's interface and tools and it would do the trick for me. I would be even willing to pay a freelance developer to achieve this for me.

Apologies if this is not the right place to post this or I am talking nonsense. This is my first post!
