Basically I am trying to give the end user more freedom/configurability on the application.
I know the SDK is not the Engine, but I like to think some cool features the SDK has alone could one day be made into engine pluggins, even if platform dependent.

It would still be good if we had the Font Creator as a JME Engine “Desktop” Plugin, and we would still provide fallback/placeholder fonts if planning on android release.

Very interesting seem like what I am asking, but couldnt find a download for it yet tho, would be cool if it gets released soon 
Yes, I was concerned about resolutions, I ended selecting the largest size possible fitting in 512x512. And when scaled down it still look great.
That c++ project, may be it could let we cache pre-rendered to the requested size, would do the trick concerning performance. And a java wrapper would be interesting, still looking for it
