Duncan,
It would be worth trying.  It should only require a few VG's.

  Essential to getting a reasonable and consistent amount of air through 
my (rather small) cockpit NACA vents! (which are located in the 
"standard" position).

  Do NACA vents have a critical Re above which they don't work well?

  I have a suspicion that a VG ahead of the NACA on top of the cowl may 
be beneficial too, as this vent seems to stall at high AoA (i.e. when 
pulling in to the climb without change of airspeed the WoT revs are not 
maintained meaning (on mine) that hot under cowl air is being consumed, 
rather than cool air from outside).

  Need to find out for sure.

    All,
    Has anyone installed Vortex Generators on their Europa Aircraft??  
If not, why not?  If you have, would you please share your findings?
    Thank you very  much.
