I'd consider another reason to want to swap to discs would be for the cosmetic look with aftermarket wheels. I dislike my drums with my aftermarket wheels...

Yes, but it is a very expensive swap for just cosmetics.

400 is cheap in my book for a full rear disc swap...

More power to you then. If the cost is worth it to you, then I say go for it. Just to most, the cost is not worth it.
In the end, it is your car, and only you have to like it.
