What is the possibility of including a Gray Jedi then?

There were greyer Jedi, especially thanks to the event that was the Clone Wars.

Even before there were some who played it a lot looser with the Jedi Code e.g. Qui Gon. 

So yes, as long as you don't completely ignore every aspect of being a Jedi :P
