Hey there,
I dont see any reason at all why you wont be successful. Unless you are thinking of an MBA, I would advise you dont invest 100s or 1000s of $ in technical/online course. Once you get in a global consulting firm they will provide ample training. Key thing is to smash the interview process, have a solid CV to get through to interview.
I ran Accenture UK & Ireland's Supply Chain and Operations practice in London, so can give you plenty of tips and insights on your aspirations. Please feel free to message me and we can discuss this in detail. Here's summary for you:
1. Accenture & Big 4 have invested heavily in their product engineering and operations capability and are growing in that space
2. They are always looking for people with complex capital projects & engineering experience; Aerospace & Manufacturing industries are the primary focus. Industry X.0 is the next big deal
3. You will have to prep like you would to get into consulting: CV, case, FIT interview etc
