How would you slow-mo this?

Here's my dilemma: I got some super-cool footage with my GoPro Hero strapped to a crop duster. I shot it at 720p 60fps. The footage overall is remarkably shake-free. I need to slow it down quite a bit and make it smooth. FWIW: The plane was at most times traveling 140-150 MPH and very low to the ground. How do I get smooth shots without losing picture quality and artifacting that something like Twixtor could produce on such a fast moving shot?
I have Premiere Pro and After Effects as part of the CS6 package. I know I can simply cut the speed 50% but what if I want to go slower? I'm trying to avoid the stuttering effect of not enough frames for the speed I want.
Another part of the problem: There are only a few GoPro 720 60fps shots in the documentary I'm shooting. Everything else is DSLR 1080p 24fps. How should I integrate the GoPro 720p and DSLR 1080p shots together... What is the workflow?
Here is a link to the unaltered 60fps footage to give you an idea of what I'm working with. BTW, about 1:35 in, it gets pretty damn cool!
Thanks in advance for any help you can offer!!!
*EDIT* The footage is a little blurred. I must have messed up the export settings since I was in a rush..

If you want your final video to be 1080 then you'll need to upres the 720 footage at some point. Magic Bullet Instant HD should do a better job than simply increasing the resolution via AE or an editing application but I'd recommend using a trial before you decide to lay down the cash:
As for going to slow-mo have you considered simply re-interpreting the footage as 24fps? This would playback at 40% of the speed of the source and also remove the frame rate concern when it comes to conforming the footage for inclusion in the edit.
