Yes. I am not 100% certain about the ordering, but custom scripts are
definitely supported, and if they specify proper dependencies for
sysvinit, those will be respected.

I suggest you try it and see what happens. An easier way of trying out
systemd than to install systemd-sysv is to just install the “systemd”
package and boot with init=/bin/systemd (which you can easily add/change
in GRUB for one boot only).

Predictable network device names are a feature of udev (not systemd),
which — as you mentioned — is not currently enabled by default. To make
use of them, you need to boot with the kernel argument net.ifnames=1.

We may enable predictable network device names by default in the future,
but not without a proper announcement about it.
