it would be cool.. and possible now with the magic bands, but it would also require additional staffing as currently they typically dont have cast members stationed at the line entrances.
agreed theres no room for additional lines on most things
an additional waterpark would be cool, but I dont see that happeneing anytime soon
especially considering they haven't added any attractions to the current waterparks since they were constructed.. so I'll take new rides over a new waterpark anyday
would love to see someone build a "thrill" waterpark in orlando.. though logically thats more of a project for universal than disney as disney caters more to families than teenagers/adults
