Addressing Rishabh's question:
If the "No SSLv3" option is enabled, then the cipher string modification is not required.
Also, to address your point of modifying the base profile: If a base profile is modified in this manner, all profiles inherited from that base profile will take the same affect.
I should also mention that v11.5.0 onwards, SSLv3 is not included in the DEFAULT ciphersuites.
