You should always be open to changing job, but that's a separate choice from whether or not to do an MBA since you can change jobs whether or not you are taking a MBA. Any smart future employer will welcome an MBA.
Why not change onto the accelerated path? They will be closer to your age, and the courses will be more engaging with better students. Of course the 3-year programme has a better range of electives, which might also help you stay on track. But I think you can also expect that even if you know some of the subjects, that the case approach will introduce you to new companies and industries.
