you could try asking in the ae expressions forum, but i believe that text properties cannot be accessed by java, so expression or scripts would not help here.
however, you can have several comp timelines open and visible at once (as many as you can fit in your monitor). as you open each comp, drag the tab in the timeline window bellow the current tab.
this should then make each timeline’s layers viewable (and selectable). just select the text layers from the various comps (holding ‘shift’), then choose the font settings from the character palette.
its still a little tedious, but not too bad.
