For sake of adding Star Gold 2 HD
If Space Crunch is not the Issue and Removing / Altering Existing LCN of a Particular Channel (read Theatre Service Channel) creating Hinderence here - then there is "One Stop Fatafat Solution" to handle the Situation.
Just Inter Change the LCN between 'Star Gold Romance' & 'Star Gold 2' and after Shuffling - easily the HD Version of Star Gold 2 HD can be included.
So as above said - the Change / Updated LCN Scenario can be :-
LCN 317 - Star Gold Romance
LCN 322 - Star Gold 2 HD
LCN 323 - Star Gold 2
