I don't see a huge benefit of converting a corner overflow into a coast to coast. With the return placed on the opposite side you won't have any surface skimming issues.

Leaving it as is would work, as this aquarium was a gift from my other half, but then it was also stipulated that the aquarium has to be quite enough so the room can still be a guest bedroom, so I was hoping that the increased surface area would result in a large weir and make the overflow quiter, as if i have a splashing overflow, i'm pretty sure the tank won't last long.
