Can ShowDown replace Dominion?

ShowDown is basically a 1 on 1 or 2 vs 2 match, that was held on a Howling Abyss 2 or 3 years back as a featured game mode. I loved how it was so fast paced. And with the loss of Dominion, which was fast paced, can we get this one? It won't be neglected as it will be similar to all the other modes where its a tower destroy, get nexus mode.

Also, if it isn't too much, can it be on the Butcher's Bridge game map. Its being unused right now, and I just thought that it might fit perfectly in synch with how Butcher's Bridge was played out in its use and lore. It would also be a fun game mode that won't last more than possibly 10-15 minutes, because its only a straight forward objective with only 1 to 2 people playing at a time.
