One Joint attack per clan in clan wars

Are you guys part of a clan that only has 10-20 people during wars, and seem to always be going up against a clan with some ridiculously high level player as their number 1? Someone that no one in your clan can beat? I think it would be really cool and add a bit of a twist on the wars to have a joint attack option. Most of the time, people who are ranked number one in clans don't get attacked, or don't get a single star on them (At least in the lower level clans). So if each clan had the option during a clan war to have a single joint attack, regulated by a leader or co-leader (meaning they pick who is able to use the clans only joint attack for the war) wars might be a lot more fun.
Obviously, There would have to be some sort of balances. so whoever is part of the joint attack will have one of their 2 attacks used. And the person being attacked will have a damage increase on their defensive buildings. For example, cannons would do an additional 10 damage each, and mortars would get an additional 2 damage per second. (Just examples, and I realize that might be underestimating the difference.) All defensive buildings would get a boost. The resource bonus would be split between the 2 players attacking if they get a star. I know it sounds like the 2 players would be over powering, but the damage increase for the defensive buildings could be directly proportional to the combined level of the 2 players attacking, meaning that it still is fair and fun. Please provide thoughts and feedback?

1> The number one is no one special. He is 2 starred too, in our clan.
2> If 3 or 4 guys come together, they can easily 3 star a maxed out th10 base. So, it will be too OP.

In many cases, I have seen wars where the number 1 guy himself is OP compared to anyone else in the clan. This might not appeal to those who are in strong clans, but for players who make a clan for a smaller group, and don't have strong troops, this could add a lot of fun to the wars. People I see sometimes complain about the difference in power. And close wars are fun, so this would help.
Also, that is why I said the increase in defense towers would be directly proportional to the combined level of the players attacking.

Seems quite interesting, it could make clan war more fair, but it could be too OP.

Well, I realize it seems OP, but this is for every clan. Even the lower ranking players could get an opportunity to use it, just depends on the leaders and co leaders. Even if they use it to 3 star the number one guy, the other clan can do it right back. Or if their lower guys are having trouble, and cant seem to attack anyone, this gives them a chance.

Another thing I don't think I mentioned, it would only be 2 people attacking. Not 3 or 4. So if they have a town hall level 10, fully maxed out, they would still have a tough time wiping them out if all the defenses have a damage increase that is proportional to the levels of the 2 players attacking. Hope that helps

I'd love to have a number of variants on CW. One idea could be to have each player having unlimited (yes) attacks per war, but only one single and diminishing set of troops. As troops died, you had fewer and fewer troops to hit with. However, damage from a previous attack carries over.. so if another player 99% one base you could use a few troops to finish it off. Troops deployed that survive the war should survive to attack again, and the logic would probably follow that you would abandon the timer on war raids. Of course, this turns the CW game into something completely new. Replacing one really interesting form of gameplay with a new one is probably just going to fail as a concept. Still, it'd be awesome to have a variety of gameplay available to distract from the usual farming/collector-scraping grind.
