Not a bad idea in any way, but unless I’m misreading something (entirely possible, I sometimes do that lol) it’s not all that different compared to the other weapons. The yellow/red aesthetic is cool but a few people have expressed interest in seeing that added as an overheat mechanic to the Boron Railgun, I think galbatorix was the first to come up with the idea.
But welcome to the community! Your idea is still pretty cool and with some work it could become pretty unique too. Hope you continue to contribute!
