Bad news :( I would definitively pay for an "A-10C v2.0" with some features now missing in the current version, including proper JDAMs mechanization and better CBUs damage model.
The point is, yesterday I was fiddling around with the A-10C folder and there are lots of lua files depicting avionics items, I'm sure not all functionality is there, but maybe it's possible to "inyect" external code into the aircraft with them, to add new features. For example, in the CDU luas, all the pages, with the labels, position, etc, were defined, maybe to add a new page and link it with new code from a different dll is not that hard after all...
Regards!
