If an Original Cartoon movie was made at the time?

[FredWolfLeonardo]

What if sometime during the height of tmnt's popularity, it was it decided that an animated tmnt film set in the continuity of the Original Cartoon was to be released in theatres?

It would have an approximate 90 minute runtime, animation typical of a theatrical Disney release rather than a Saturday Morning cartoon, and have all of the major characters in it reprised by their original VAs (the turtles, chanel six crew and technodrome villains.

What do you think the film would've been like in terms of story and how well would it be recieved both at the box office and critically in this hypothetical scenario?
