Nothing forces you to define the IP addresses in LXC's config.
You can perfectly go with a single:

lxc.network.type=veth
lxc.network.link=br0
lxc.network.flags=up
lxc.network.hwaddr = [...]:ed:d8

Then define the addresses in /etc/network/interfaces in the container
with something like:
auto eth0
iface eth0 inet static
    address ...
    netmask ...
    gateway ...

auto eth0:0
iface eth0:0 inet static
    address ...
    netmask ...

No idea, I don't know your network :)
