As for RMC Eagle, they could always shorten the track length. Iron Rattler and Twisted Colossus didn't use the whole layout. I know this one is an out-and-back, but there's nothing saying they have to go all the way out.
The log flumes are very old, from a time when log flumes were much more popular, and rarely run at the same time anymore.
My stance is this: I think an RMC Eagle would be great, even with Goliath right down the midway. And I'm sure they could make it different enough that it would be great to have both. BUT, I feel like if Six Flags is going to invest in another RMC they'd get a lot more bang for their buck in a park where there wasn't a similar ride 500 feet away. (And even if you don't think it's a similar ride, the general public would...)
