In that case you may as well leave the unique names in place and set up
recognisable aliases.

There are no config files to edit with the predictable names, the names
are created from the physical location of the port. That's why they are
called predictable, unless you move the NIC to a different PCI slot, it
will always have the same name, no matter what other hardware you add or
remove. Yes, the names are cumbersome, but they have to be like that to
guarantee their uniqueness. How often you you have to type interface
names anyway, and how many of those are in a shell with tab completion
that takes care of it for you?

The names are ugly, but that's about their only sin.
