Exactly....
What's more realistic is you have to get a single /48 of PI space for
people to carry that globally.

And if you have 5 discontiguous networks, what the RIRs should do is
carve a /44 out for your
present and future PI allocations   and issue you    the  8  /48s;
the PI /48 routing slots
that you have justified need for --  arranged so that they fall within
the same /45.
