When It comes to new weapons everyone would be pleased to see it. the rules restricting weapons are for the safety of the Roboteers or audience, or they are to make sure the weapon does not stop the fight early entanglement weapons radio interference etc.
What I would say about new weapons is they take several years to perfect and development costs a lot!
Many people in this game are professionals in science and engineering. If it's going to be effective and reliable they would have thought about it or something similar, please develop it but be aware you may find there is a good reason it hasn't been put into practice before.
