Yes, but if you do that, your color image will be essentially red
(only the IR layer will be exposed... like a normal color film with
a red flash)

On the other hand, pushing a film increase contrast... and the
new color IR film is IMHO *very* contrasted (and too much red)
in E6...

I suggest two solutions
   - push the film, but process in EA5 : probably difficult, but
     look at your national Geographic Survey, or some other pro
     in Aerial Photography : they use a lot of EA5 for aerial
     color IR film (I have asked IGN in France and they can do
     that... at 150 FF, = approx. US$ 25) so it's also expensive !
   - use only a "light" yellow filter and expose at 320 ISO TTL
     eventually with a tripod : I guess that the movment of
     dancers can give some interesting effects...
