Rowly,

My uneducated opinion is stock now. I stocked my trout 2 weeks ago (SE Quebec). The temperature was about 63F at the time also. The trout were hiting insects on the surface within 2 minutes from release. I've caught & released some since then and all seem to have adapted without any problems.

I'd think if you let temperature drop too low and the fish are too lethargic when transfered they may have a hard time finding winter cover/habitat and may have a harder time adjusting than if you stock now. With Walleye this may not be an issue as they are cool water fish but, I'm certain at 63F your in the right range to stock.
