"not updated" means it will not work no matter how hard you try. If there was any way I'm sure someone would've made it public already.
There are lots mods that add features RP had though, MFR RedNet cable is a good replacement for RP's wiring (imho it's way better). I think there is also a mod that adds microblocks in Unleashed and there are Abyssal stone and Quarried stone (not sure which mod adds them) to replace the stones RP had. BoP also has volcanic biomes if you really want a burning wasteland. ExtraUtilities transfer pipes are a decent replacement for the RP tubes (not as good, but they get the job done with 0 chance of "leaking") and don't forget AE either (imho the best mod for item organization there is atm). I think the only real thing that's missing in Unleashed is a replacement for Frames and maybe some smaller things RP had, but a lot of it has at least decent replacements (not counting all the stuff outside Unleashed that replaces just about everything).
