No heresy then :) Yes indeed your parallel plate capacitor arrangement on the back side (right hand side) of the cathode is capable of increasing electron density there, good idea!
A few comments: 1/ Any point in using two dielectric materials, why not just metallize the right hand side of the thin glass to make the HV anode? 2/ Assuming you agree with 1/, the charge density on the RHS of the cathode only depends on the ratio of the HV to the thickness of the dielectric and on the dielectric constant, the absolute value of the HV doesn't matter right? 3/ Why not make the HV anode in the shape of a grid, or a uniform metallization with a small hole, so you could shine the laser at 90° to the cathode?
