War-matching using combined clans' defensive bases for each clan

What if (throwing the idea out there) when matching for a war, it took account of players on both sides of the match, and created dummy accounts to make the wars perfectly fair (for defense anyway)

10 person war example:

CLAN A
a1,a2,a3,a4,a5,a6,a7,a8,a9,a10
CLAN B
b1,b2,b3,b4,b5,b6,b7,b8,b9,b10

Then we make a 20 base war where the bases consist of the clan's own bases and extra dummy bases (in bold):

CLANA
a1,b1,a2,b2 ... a9,b9,a10,b10
CLANB
a1,b1,a2,b2 ... a9,b9,a10,b10

So we'd see twice as many bases to attack in a war (and presumably need to be allowed extra attacks, I think three attacks each would probably suffice)
Leaders and Coleaders would be able to edit those dummy bases so they weren't exact replicas of the opposition.

This could mean that the ONLY thing we had to match wars on would be offensive level, because defensive levels would be matched perfectly fairly.

Thoughts?

(and apologies that I couldn't think of a snappy title)
