A seal and fucked are two very different prices.

I did this once with a head gasket. Limped home. Little did I know that I was adding oil to the sump safely but the gasket was conveniently adding coolant to the sump as well.

Bye bye bottom end.

If you are going to stuff a new box in there drive it granny style to home. You still might need a tow anyway and now you have a really fucked box. Just trying to be the voice of reason.
