More official maps, or less official maps?

[V-Man]

Not my idea, but I keep thinking this solves the problem of "unfair" maps without having to revise them:

Clan A vs. Clan B:
Clan A picks map/mode A
They play map/mode A, |A| on CLA and B} on RVSF.
They then play map/mode A, B} on CLA and |A| on RVSF.
Then
Clan B picks map/mode B
They play map/mode B, |A| on CLA and B} on RVSF.
They then play map/mode B, B} on CLA and |A| on RVSF.

Other than being the equivalent length of two clan matches (and that is definitely fixable), how is this not a complete solution?
