Broad blade Weapons, specifically Chisa sig and new 5 star standard

I used my free 10 weapon pull from the anniversary and decided to yolo pull on the weapon banner because surely I wouldn’t get the weapon after being at 0 pity from pulling for hiyuki weapon. But WuWa said yolo right back and now I got Chisa sig (I have Chisa luckily). But my Chisa already uses the new 5 star standard which is just as comparable apparently. So now I have a new 5 star standard banner broad blade that doesn’t have a home since I already have the original 5 star standard banner broad blade on my other character. Should I switch it out?
