I say it's better to avoid merging with Smallville because the repetitive name-sharing can be really out of hand. I also think it's best to avoid merging with wikias that had not yet had a crossover outside of Crisis on Infinite Earths (Smallville included). Plus, there is the mess of merging every single page of another wiki just because a few characters crossed over. For example, all the characters on DCAU (DC Animated Universe), which already is a crossover wiki itself and we'd have to incorporate every TV show from that universe into one wiki. I think it's best to redirect their previous biography prior to Crisis to the wikia they belong and only include their Crisis on Infinite Earths biography here. Having several wikias commited to the same characters is not uncommon such as with MCU's characters so I we should borrow that for the time being and think this over a bit more before deciding to merge large wikias simply because a few characters crossed over.
