You don't need an ASN to use PI space.

We have a few customers in the same situation. So we obtained a PI
prefix for them, which costs next to nothing in the RIPE region at
least, and advertise the prefix on their behalf (and in the cases where
there's a second upstream, the second upstream does the same). Works
perfectly well, and is much less complex than anything solution
involving ULA, NAT, multiple prefixes on the hosts, or whatever. The
customer just gets a bunch of addresses he can use in perpetuity.
