Why not, copy the table into another table? eg
create table MYTABLE_COPY as select * from MYTABLE;

Remove the table from the replication set...

I'm not sure if you can do this in such a way that the removal from the 
set happens before the data from the slave's table is actually deleted.

Hopefully, someone who knows Slony better should be able to provide a 
better answer on this.
