Donna/Kory - Hee hee! I can see it, but I'm not there yet. Donna/Kyle makes me really, really nervous, because Donna dies a lot and women die a lot around Kyle. XD
Countdown should have had WAY more complex interaction between the two. I hope they interact in the future, really, because his crush on her is actually very touching to me, considering how motherly she is.
Yes! Also, to me, Donna/Jason is a lot like the crush-on-an-older-woman thing that Dick has for Babs, so it seems familiar and right. They had a little Titans history before, had the Countdown history after, and have being dead-but-got-better in common. I can see it starting off due to Donna's protective nature and growing from there. Someone's got to pull him from the path he's on, here's hoping against hope it's Donna.
