Are stators dispensed with?
There has been talk that contra-rotation between the HP and IP spools could remove the need for one or even two stator stages.
But that also happens to be where at least the HP bearings have to be rigidly supported. Surrounding a bearing support with stators allows for plenty of structure to keep it properly anchored. When you don't have stators, what's going to do the job? Remember that efficiency requires small clearances between the stages.
