Have you checked out bridge? I'm learning to work with it now. I think you can adjust the collision box size effectively making the sword bigger? There are probably other options hidden away in there. I wish I could give more pointed advice.

I’m having trouble figuring out how to create a new weapon that is both longer and wider than the vanilla swords. Any advice?
