Magluvin, I keep it in mind for the next modification, i am waiting for the ultra capacitors and run my view of the Q2 in actual configuration first.
modifications are all time on the way, thank again, Marc

Yes; the optical sensor could run the SSR on its own but here is the challenge-
With a reed switch; pulse width is easily adjusted by changing the distance between the reed and magnets.

The optical sensor will need a pulse width adjustment.
In layman's terms:
A knob that makes the optical gap (in disk) to appear 'bigger' and, if possible, also 'smaller'.

And I believe this would just be a timing capacitor or 555 timer or, maybe, just a resistance in the right place.
The Q2 uses a couple 22k resistors, before the relay, to change pulse time.
Instructions say- "(2) 2200 ohm resistors in series are used to provide the option of jumping one, or both, for an extended pulse time."
Although I believe this would also be effected by voltage and would prefer something more stable.

Or maybe some way to incorporate the optical sensor into an existing PWM such as this motor controller I have on my shelf-

From the looks of it, the optical sensor shown would drive the relay on its own as shown. Just apply 5v to one side of the relay control and the same circuit I posted, connect the output of it to the other control line of the relay. 5 to 30ma is fine I believe.  I dont have an ssr to try.

But if you have a Radioshack near by.......

It should work the same as the circuit device I posted, just separate parts, led and photo transistor.

I think I mentioned to use 2 black plastic disks with holes or slots sandwiched together so that one could be adjusted to make the slot or holes smaller or larger.

This is a really good concept. Thank you. 

Reliable and elegant in its simplicity.
Easy to implement although not adjustable while running.
And may incorporate reference marks on the disk to indicate whatever the current gap is.

So; is there a schematic for the simplest way to operate the SSR directly from a basic, four wire, optical sensor?
