   First, G doesn't appear in the Planck formula.  If we imagine changing   
   the value of G, we would not change the Planck formula, but would change   
   the appearance of Wheeler's vacuum, noticeably if G were changed   
   drastically (ignoring for the moment other effects of such a change).   
   There would then be a difference which, as you argue, we don't observe   
   today.  My guess is that the Planck formula would still work, but then   
   give results different to what you expect from the Wheeler vacuum.   
      
   In another sense, it is not a coincidence that Hawking radiation has a   
   black-body spectrum, so perhaps at some level this equivalence is   
   already there, though perhaps not in the form you describe.   
      
   Analogs of cosmological redshift in particle accelerators?  I've never   
   heard of such a thing.
