Hello Dedy,
As you mentioned, you should not change the Silk UI Components, to keep your Silk easly upgradable.
In order to extend SIlk, you need to copy the pattern to your application.
Since the pattern you want to change uses a Private Webblock, you also need to copy that private webblock to your own application, and then use that webblock on your structure element.
Nevertheless, for us to better understand your usecase can you please tell us what is the structure you would like to implement, that can use the same CSS base of the remaining structures ?
Cheers,
Samuel Jesus
