Yes, but iproute already supports bind-mounting files in /etc/, so I just need to create /etc/netns/$NAMESPACE/network/interfaces and everything works.

I tried hard, but this cannot work because "ip netns exec" creates every
time a new ephemeral mount namespace:
unshare(CLONE_NEWNS) = 0
mount("", "/", 0x8089fca, MS_REC|MS_SLAVE, NULL) = 0

No matter if you enter the namespace manually or magically by ifupdown
itself you need a different state file.
I think that my approach of explicitly entering the namespace feels more
natural because you need to use the same command anyway to start your
daemons etc.
