I think, that it needs a more general discussion. I see no license 
information in the opens___.ttf file. But I guess, that SUN/Oracle holds 
the copyright on that font. So it might be, that it is not possible to 
add new symbols.

My suggestion -not to you personally but in general- is to deliver the 
STIX fonts and change totally from OpenSymbol to STIX. The STIX fonts 
have all the math symbols someone needs.

Kind regards
