John, Are you just discovering that trick?
In general: R*C = L/R
I was using that to make inductive drivers for modems ~1977.
But it dates MANY years back to GenRad bridge designs.

I think I'd seen it a long time ago, and forgot. I started thinking
about the step-response currents in each leg and slapped meself upside
the head. Duh.
We just rediscovered it in the context of split-path amplifiers. As a
practical matter, to make it really precise, one would probably have
to use a little Coilcraft slug-tuned inductor as part of L, to tweak
things up. There will be capacitive parasitics in L, too, a more
serious issue if this is to be truly wideband, like DC to 1 GHz for
starters.
