Can I put BBP drums on my 69 ?

At this point it is just a curiosity.
I was thinking that if I need to get new drums maybe I could just order newer LBP drums if they were interchangeable.
And when I order new axles I would get LBP in those.

This turns out not to be the case so I will just stick with the current setup.

And yes I know how to do the Disc swap... that 68 Fastback has 4 wheel discs...
