Enthusiasts as a whole disregard flumes, I myself am no great fan, but the public love them!!
Most people would expect to find one at a park the size of AT. Of course, the now 35 year old trough track at the park is waaaaay overdue going to the scrap heap but if the footers are already in the woodland it just seems a totally lost opportunity to build a new structure surely? They could even cut out the meandering sections without needing to dig new footers. Imagine a ride like Chiapas weaving in and out of the proposed woodie? Modern flumes don't even need a clunky turntable either, so space would be no issue.
Alas, it's Merlin. Never going to happen.
