Personally I'd say release it as an alternate version assuming the gameplay's identical to the previous Stand Guard release, and let people pick their font of choice.
The problem with that is that I had to edit the script in places, to make sure the text didn't overflow into a trailing page. A lot of lines were changed, so it's technically not the same script as 4.0.
And I prefer this font; it goes along with the Menu Font, and changing the two pixels of space after every letter to one really makes it look nice.
Also, when I'm old and my eyes are ruined, I'll still be able to play it.
