DPOS DACs as bitcoin sidechains?

[cob]

My daily mind numbing tasks are always assisted by LTB podcast.
My midnight reading has been coindesk.
This got me thinking more and more about sidechains.
I think they might be onto something here. It appears to be WAY more promising than mastercoin or any other protocol built on top of bitcoin.
Bitcoin of course is an unprofitable DAC that pays miners for security. So here is my question to those with a better grasp of all of this.

Do you think there is a way to make a profitable DAC of a sidechain? Where shares aren't diluted, inflation is absent from the sidechain DAC and people can still get their coins in and out of the side chain via the 2 way peg.
This would eliminate exchanges and open up the market of each DAC to everyone using btc.

Thoughts?
