I'd research lathe tool turrets some more, there's a reason all the commercial ones don't work like that, if you need to centre drill, pilot drill and finish drill your bore then ream it how will you do that and face the end and put a shoulder on the OD and part off?
And that's a pretty simple part! Try to avoid designing something that is NBG as soon as it's finished.
