It might work in a red state. Dems around here are pretty conservative - they have to be. On the other hand, I don't know if I could really bring myself to vote for a Dem. It just seems wrong :-)
I was more interested in targeting the more extreme fundamentalist Republicans. Santorum, for example, isn't fundie, but he's been outspokenly anti-evolution, and he's in trouble anyway. It would be better to target such guys in a primary, though.

I think you're right on both counts...it would have to be a red state, if at all and targeting the primaries would be a better approach.
It wouldn't work. It's like trying to move a 300 ton marshmallow (Ghost Busters, anyone?). Those who are not absorbed are alienated.
A third party seems most logical, but attempts so far have been pretty dismal failures.
