I get the idea; not sure how much other interest there is, and I think grampaglasses is the only moderator who would have to create it. Curious to see the speedrun - any chance you are planning on updating your Any% or any of the existing categories?
I have no issues with it as all I can find says it is truly a reskin (I don't see why Hamumu would have made any programming changes). I will accept it and put a note in for the run. Worst case we determine there is some significant difference and we can make an alternate category under the Robot Wants umbrella.
If you run it, I bet someone would add it as a category.
And there is a Discord for discussion and camaraderie: https://discord.gg/EVsvUxZ
I don't see why there should be a different series for the other Vex games; even Vex Mobile could be included in this series. The games themselves are still separate, and they are all thematically Vex games.
But it's up to the moderators to decide. I'd support adding them to the Vex series as it is, though.
