Mirroring tiny currents in strong inversion?

I am working in an old process--0.6 um--and I have an application where I want to mirror out some very small currents (e.g. ~50 nA). I actually want to keep this in strong inversion to keep decent matching. Can I just have a bunch of series links to eventually get to the long L that I need? Is there a limit?

Most important question: Am I going about this the right way?
