Default Product detector for Hallicrafters S40A

I am considering adding a product detector to my S40A. Has anyone used a
6SN7 to replace the 6J5 BFO and feed the IF signal to the grid of the second
triode with the cathodes tied together? The original oscillator circuitry
would be wired to the first triode. Audio from the plate resistor of the
second triode (after IF filtering).
