the only thing that works is a CPFP (Child Pays for Parent) from the receiving party
I already test that and it is still Replaceable, I did 10 CPFP in a row
A (Original TX)-> B (CPFP )-> C (CPFP )-> D (CPFP )-> E (CPFP )-> ....
and then
A (TX RFB) -> X
And if the fee is bigger and the miners include it on its block and mine it, then all the previous CPFP are Replaced as they never happened in first place.
