You wish to supply tiny charged particles to supply the effect we 
call light.  You *are* obviating the photon, since "photon" is 
simply a label for a specific set of properties.

A discrete behavior obviates any "subcontinuum" upon which the 
discrete behavior needs to look like a photon.

Photoelectric effect does not permit any sort of continuum wave.

That too.

No.  It does not agree with experimental evidence.  Now what you 
are proposing is very close to "virtual photons"; except they are 
of exactly zero size, have no net charge (even though they are 
responsible for carrying charge effects between charged 
particles), and also have no mass.

Let's see if you can do as you require of others.
