It should work WoL is just a special broadcast packet. The bridge will have wireless connection up all the time and it should just translate these packets.
Microsoft has support for wake on wireless lan but this is some special thing they have done but it is a option if your motherboard supports it and you mess with the registry. Still this is not really wake on lan because it assumes you have a microsoft os which means it is really some form of advanced suspend because a machine has no concept of OS when it is turned off and before it reads the boot sector to tell is what image to load.
