If I send a signal from the RCA outputs on my HU at let's say 600 Hz LP to
my amp to drive a midwoofer, would I run into any problems by then sending
this signal via the amp's RCA outputs to a second amp which I will then use
its internal xover to LP at 80Hz (or whatever) for a sub?

No worries. Since the two crossover points are almost three octaves
apart, It will make no difference to the 80 Hz crossover whether its
input is full-range or capped at 600 Hz.

You'll probably want some kind of high-pass filter for your
midwoofers, so they're not trying to reproduce low notes that would be
best suited for the subwoofer. If the amp powering your midwoofer has
a high-pass filter, I'd set it at about 100-120 Hz.

I thought this was probably the case. And yes, I'll be using my amp to HP
the midwoofers. Thanks.
