I mean, it kind of should have been!
Had Springfield as an entire land been conceived of and implemented at the same time as the ride, the ideal scenario would have involved getting rid of the building, putting a new ride system in its place, and then building Springfield around that.
I think building Springfield when they did extended the life of the ride, certainly, and it's a nice little land (I'd argue it's kind of underrated, even though I don't care for the ride all that much), but a completely fresh start in that area of the park would do some real good.
