Legal?  In the sense of "any string is legal", yes; as is anything else.  The 
implementation question to answer is whether it's useful or renderable, and if so, how.

The independent vowel followed by a halant could be interpreted as a graphical answer 
to the question, "What is the sound of one vowel silenced?"
