When I say 'I don't know', I mean you are the first person I know to use the 'Blower Motor' like that. I can tell from your posts that you are an intelligent man with excellent ideas, and strong knowledge.
Let us know how it works out, so we to can benefit from your ideas.

Exactamundo!
Given the shape of the shroud, I expect the airflow to be concentrated along the outer edge of the heatercore (and yes, possibly cyclonic): I just hope that there's no reflow within the center area of the core. I might have to put a bunch of little ribbons to observe the actual airflow. Worse case, I'll have to block the center area of the core, but that's really no big deal, because the airflow will most certainly be there, and the core is still relatively large, at 6" by 8". No big loss.
Right now the main issue I have is connecting the shroud to the core, but it's a minor problem. Mounting the blower is resolved, it just needs to be done.
The pic above looks a lot like JFettig's implementation of a blower on a core. Very easy to do, it's just hard to find the motorized impeller for a decent price. Allelectronics.com had one for a while, but it was seriously under-rated, as I discovered here:
