There's *nothing* you can't do if you run PPP over your serial
connections, they'd have a full TCP/IP stack and you could ping,
portscsan, ftp, ssh to your hearts content ... not that I suspect you'd
want to.

However I guess must people here are left wondering why you think you
need absolute network isolation for a handful of rPis that, let's face
it,  are unlikely to be running fort knox, or a nuclear power plant, and
that you could likely get a suitable level of isolation for your
purposes over a single ethernet port using VLANs ...
