yes, you can use jsfl to change all your static text.
Isn't jsfl only available in FP CC? If in an older version of Flash Pro try saving your fla file as an uncompressed .xfl file. Then you could try text searching down the fonts and manually changing their name. Make a backup of your fla first though. In the past this has helped me find particular fonts hidden within assets in a large fla. Then load it and resave back to an .fla.
jsfl predates as3 (ie, it predates flash cs3).
