Those tabs are very, very goofy looking.
If they were my models, I would definitely cut them off. I would probably mount them on a 1/8" clear plastic rod after slowly, and carefully, and paintstakingly dremelling out a notch in the center. Yes, I know they're white metal.
You also could, if you were feeling ambitions, do what
this guy did.
I don't sell my models so I cannot speak to the resale considerations.
