Nope. The spectral response is unique, and while you can do neat 
things in Photoshop, correct IR simulations isn't one of them. It 
also depends on what IR filter you put on the camera. If you could 
get an IR colour film that had equal sensitivity up to 1000nm or so, 
then you could use the channel mixer effectively.

I shot the following with the M8 and an 87 filter at 1250 ISO, 
handheld. I don't know for sure that the production model will be 
able to do the same, but I hope so.

I shoot (or shot) a lot of HIE in 35, 4x5 and also Maco 820c and 
Konica 750, but compared with those the M8 was way easier (and 
cheaper). Only the 4x5 HIE gave higher quality results.

This is the only picture from the pre-production M8 I'm posting, as 
an illustration and not as either a pictorial masterpiece or example 
of the M8's quality. :-)
