you can think that if you like
But the typical shift drum has a groove cut in it that the detent ball will drop into when it is in neutral. You can add another groove between, say, 5th and 6th (or 3rd and 4th) with little more than a dremel and some dissection, but getting the new groove located accurately is the challenging part since you basically get one chance.
I'd need to see a diagram to imagine this bolt is anything other than a bolt that pushes on a spring that pushes on a ballbearing that is waiting for the neutral groove on the shifter to come around again.
