You have 2 choices to discuss among yourselves: 1) Keep it as is 2) Increase size and dimensions for a bigger canvas (mostly applies to GFX artists who will likely be doing your sets) Why any size increase? If you guys just opt for a file size increase, it means bigger?, longer gifs, I guess. If you guys opt for both, 2) pretty much covers why. Nothing too obnoxiously huge, I guess, but it's not like everyone will whore the new size out unless they're attention sluts (Hi, Josuke! Much love.) Ultimately, you're going to be staring at these sets/sigs (and have the option to turn it off) so it's up to you guys. Go wild, kids (but don't go wild).
