I think it is going to be gain challenged now. But we should agree on some specs.
The card probably is .9 volts peak to peak (. as opposed to 3.4 volts. So should we target .9?
I think Panasonic has the WM61 at -35 dB which I make out to be 35 mv pp at a SPL of 94. so a gain of about 25?
But the gain also depends on the impedance of the mic and the input to the circuit so we need to nail down the power and the resistor to the mic then we can play with the preamp to get the desired results.
