Get some Epoxy (JB weld) and fill it up, make sure there are NO air gaps, if there are i think the JB weld will just shatter, which will end up in freewheel mode again (but crunchier lol).
FWIW, lead has a much much lower strength, in compression, than JB weld. Heating up the steel cassette body will do nothing to it except burn out all the grease.
