But I'm under the assumption that you can sbf from anything to anything. It's done before the rom gets loaded at the fastboot screen. I also believe that the kernels for .217 ICS and 4.1.1 CM10 are the same, so fastbooting to .217 shouldn't be an issue. FYI, I've switched between Eclipse (4.0.4) and AOKP (4.1.1) many times without any issues.
Finally, is it even possible to delete the original non-safe backup that is created when you switch to safe mode?
