A last resort would be hooking up a MOSFET as a simple amplifier --
again, you're not worried about linearity or any such niceties, but
you'd still need a good match for your MOSFET's threshold voltage...
some real measurements to replace the WAGes would

Absolutely not. The A/D is eight bits, with an input range spanning
0 - 3.3V, so the best you
can hope for is about 13 mV per LSB. I would guess actual accuracy
to be closer to 26

isolated in relation to the DC end. An earthed AC plug in some
countries produces a more reliable and positive insertion and anchoring.
