I don't think I fully understand your question here. Every SCL is confined in its own root under /opt/.../name/root. So you can either do two SCLs, each with different Ruby version; one SCL with version different then what's in the system; or place both versions into the system, where I see the significant maintenance burden. The last option is the only currently possible in Fedora, but Ruby-SIG is not going to do that.
Does that answer it?
