I really don't understand the point of resetting it if there is not a clear understanding of what roll it will serve within the organization moving forward and a recommended path for how projects will interact with it.
If it is only going to be a proxy for maven central, then that is fine and you should go for it, but if you're planning on having projects actually deploy to it and/or build out the story for syncing to maven central then all of that should be ironed out ahead of time and wired up accordingly.
Maven repositories are meant to be durable and exist forever, unlike orbit repositories that are transitory and exist for small windows of time. If you screw something up with Orbit then no biggy, it will eventually just disappear and problem solved. With a maven repository once it is released it is locked away for time eternal, which is why I am such a strong proponent of having staging repositories so upon release you can give things a pre-flight check before releasing it and locking it down.
Once you set this up and take ownership of it you are making a contract with anyone that uses it that you will support the stuff in there from that point on. None of this disappearing repository stuff where you check out an old tag and some repository you built against is now missing and perhaps replaced with a different version of some dependency.
