No need for all that, just add a resistor to THCAD input to raise the required current for triggering.
What voltage is ohmic using?

5 volt Thad
24 volt power supply.

I would put at least two of those 5K resistors in parallel, in parallel with the input of THCAD.

You mean across positive and negative of the Thad?

Yes, across the THCAD input side.

What resistor value would you use between positive of the isolated power supply and the positive input of the THCAD ?
