People, people.. You're making this much too complicated.
Solution? Agree with the opponent on whether or not Driz+SwSw is allowed for each battle you have.
Or..
We can all ignore the ban completely as it's only a "less-complex ban" since the moderators think we're idiots and can't remember what's banned or not (Ludi/Kingdra/Kabu + Drizzle, for example; how hard is it to remember THREE Pokemon that would be banned with Drizzle?), because honestly, if a complex ban helps the metagame, then make a complex ban. Does Blaze Blaziken 6-0 teams? I think not. In UU, it was slightly decent, but you just rip it out of UU because of its second ability (which it wouldn't even be using), but the moderators decide to not make a complex ban on Blazi so Blaze Blaziken is allowed, but SpeBoost isn't. I THINK we can tell whether or not we're using the allowed Blaze-ken, or the banned SB-ken, but mods think that we can't tell the difference between them when making teams, and just bans both of them.
Tl;dr - Mods believe that we don't have the brain capacity to remember what's banned or not about a certain Pokemon/strategy, so they ban everything related to them (Both Blazikens when only one is broken, etc.)
Also it's 3 AM as I typed this, so sorry if I'm completely wrong
