Adobe Arabic

Using Adobe Arabic as template! is it possible ?

Generating an Arabic font is really complicated process, i was thinking is it possible - or legal - to make it easier using Adobe Arabic font and its sample VOLT code??

* I mean changing all the glyph shapes in Fontlap.
* generating a .ttf file.
* opening it withe VOLT and import sample VOLT code provided by Thomas Phinney. then just making edits to it.

It's sound simple, but i don't know if this -so easy- method is bug-free or even legal!? what do guys think?
