I think this is better known as pre-flash, and the Multiblitz (likely 
Bogen in the USA) slide-duplicating stand offers this feature. Not 
sure how this is done safely with an ordinary flash....but I am 
pretty sure you will be testing on a different film than EIR....;-))

I think cheap and AR-5 are technically mutually exclusive, as the 
entire process screams CALIBRATION and SCIENTIFIC CONSISTENCY all 
over the place....8-))
This is also the background of the Kodak recommendation to darkload 
EIR (which has promptly been swallowed by all major magazines, 
without any testing....fools). 

One other thing I want to test one day is the effect of ND filters on 
EIR. ND, just as polaroid, is known to have little effect on infrared, 
hence the entire visible spectrum is surpressed, while the IR 
spectrum remains equally intensive. Not sure what it will do for 
contrast, but the red tones should be stronger, at the expense of all 
others....I think....:-))
