It would certainly be worth a try. I was employed as a student on some government spruce seeding trial, and I can't remember exactly how it worked out but seems to me that it was successful.
Nowadays, I'm a bit of a contradiction because I love trees, but I'm the guy out there in the forests making it possible for large corporations to cut it all down in a most efficient manner. Everything is replanted of course, but usually with a monoculture. Does make me wonder why aerial seeding isn't used more...
