I didn't try it, but I don't think you can even do
that with kernel/brctl alone. A bridge slave needs an
ifindex, and alias interfaces don't have their own separate
Thus, you are anyway enslaving the whole eth0.

So the next question. Can I have a bridge with eth0 *and* an eth0:0
alias and expect things to work?

Interface aliases are concerned with the IP configuration (Layer 3) of
the device. Once you enslave the device eth0 to a bridge, it has no
more layer 3 properties and thus it makes no sense to have IP
configuration there.

Enslave eth0 and configure your IP addresses on the bridge device
itself, like having a "br0:0" ...
