From my understanding s-off is forever unless you change it back yourself manually.
You can flash a customized firmware in order to not lose your recovery. There are some available if you do a quick search(I don't have the links convenient right now).
If you are s-off (it seems like you are) then you should be able to flash a radio in recovery if you want. You would just need a flashable version of the radio. There are some of those floating around in here (I believe some in the same post as the firmware) as well.
Hope that helps.
