How can you modifie a current mirror to work for negative voltages?

A usual NPN current mirror looks like this:

But I want to use Vout for negative voltages, e.g negative voltage regulator output to meet minimum load requirements. (the resistor dividers are over 50k in total), so how can you change it to work with negative voltages?
