In BK, when you are categorized within the same class, then you will receive the same disposition. This is evidenced by all the PORs that came out as well as the most recent PR issued re: settlement (now failed).
If Ps get cancelled, so will Ks. If Ps get converted, so will Ks.
There are some that say Ks can only get cash, but where is the cash coming from? If there was cash to pay Ks, then Ps will receive the same treatment. Same class = same disposition.
When there is no cash in the Estate, the Estate distributes equivalent value.
