What I would really need to do is fit the one-piece fan blade assembly
on back to front (as well as reversing the motor), but the fan blade
assembly is not designed to be attached the other way around.

If it is a shaded-pole induction motor, it will not be possible to run
it in reveres unless you dismantle the whole assembly and put the stator
in the other way around. It would be more effective to get a spare fan
boss and make new blades for it.

It's not shaded pole. It has two sets of windings perpendicular to each
other, and a capacitor which I believe is in series with one set of
windings.

In that case it ought to be reversible - but I would still consider
making a replacement fan if you want a reasonably efficient reversed
airflow..
