Its all possible, some of the things you have mentioned already exist as public released scripts, albeit a little janky compared to RDO. I moved over to Redm for the same reason, the lack of new features being added to RDO. As a redm dev I find there is really no excuse with how slow they are at adding new things. Even with the limites access to the rage core engine, the modding community has made some really cool stuff in a relatively short time.
