The problem with doing wifi weird bridge mode where you are on both networks leads to performance issues on busy networks because you are necessarily on the same channels.

It might be worth giving that up since then existing hardware is usable.

Yeah, it's definitely suboptimal but it seems to work. If it's easy to have a second radio then you should probably have one. On the other hand, urban areas are usually so saturated with access points that using a separate channel might not gain you much.
