Good decision, I'd say.

Could it be helpful to boot the Indys via network (incl. root FS on NFS)
when further debugging this or will this still lead to a panic when the
described transfers happen to the zuluscsi which then doesn't host the
actually used root FS?

I don't know how to network boot these with NetBSD, but if it's the same
or similar to how OpenBSD does it, you can find a recent boot log on [1],
together with the needed PROM configuration. Requires DHCP, TFTP (for
initial load of elf-to-ecoff loader and kernel by the PROM), RARP,
Bootparams, NFS (for getting the mount information for and mounting the
root FS) and possibly DNS services on the server side.

HTH.
