Just a quick note on the new slot.it type C chip... I love it and am fully supportive of it... but... even aside from the fact that it won't be out for a few months, it will still be an unknown entity as far as how it works and such. I would suggest that the next proxy not consider this in any way. Give it until the next one in a year, when at least the early issues are worked out with firmware updates. Also, right now, if the idea is to use it on both Carrera and SSD tracks in the same proxy, it looks like the firmware needs to change whenever it changes tracks, at least at first. I don't think it's reasonable to expect track hosts to upload firmware into all the cars prior to racing, even if they have a device that is capable of doing so (a recent smartphone/tablet). It is hoped that a future firmware will be able to run on any track without any intervention between them. Until then, let's stick with what we know works.
That said, I'm on board with opening it up to more cars. Maybe have two classes, one for stock Carrera, and one that's open. It can often be fun to see what people do with cars when all holds are not barred.
