I don't understand. There are no actual aliases since kernel 2.2 and an attempt to add "br0:1 with address 10.10.10.2/24" using ifconfig should result in the same configuration as ip addr add 10.10.10.2/24 brd + label br0:1 dev br0 where the "label br0:1" part only adds a label which allows ifconfig to see the new address. As both addresses share the same range, you don't even have to worry about source address as primary address (10.10.10.1 - or first one added in general) will be used unless specified otherwise.
