With some decent code, this could measure capacitance (uF range, not
pFs), true esr, resistance, millivolts, possibly a useful range of
inductances. It could find shorted pcb traces and maybe plot diode
curves.

The dac is optional, and the adc might be inside the uP.

This is a stage 0 brainstorm. Of course you can find objections, but
I'd prefer improvements.

What's the purpose of the SSR, just to have two ranges of current
source? If so, it might be cheaper and more accurate to have two
sources in parallel.
