Compatibility of 70mm HIE bulk with 4x5 graphic film holder for 70mm film?

[George Ling <master@xxxxxxxx>]

I noticed a 70mm film holder device in a camera store today that is like
a *graphic 23* film holder for 4x5 cameras with graflock backs.  It has
a lever film advance and a counter that counts to some 50 frames.  

When I opened the cover, it has a carrier assembly inside, on which
there are two rollers on either side, and two canisters take-up slots in
the middle. 

The pressure plate, which is between the two rollers, is a piece of
metal but is *not* spring backed. In addition, it has 10 holes (about
5mm dia. each) punched on it in this configuration:

      |                           |
      ----------------------------- 

A wishful thinking: if I load a canister with Kodak's HIE 70mm bulk, I
would then have 50 shots without changing film.  

Remembering from past IR e-mails that pressure plates with patterns on
it might create a *pattern* onto exposed HIE film, because the film does
not have any anti-halation backing. My question is "would this 10 holes
create a *pattern* onto exposed HIE film also?  If anybody has
experience with this kind of 4x5 graphic film holder and 70mm HIE film,
please share his/her experience with me.  Thanks in advance.
