It has to do with the hose-routing and developing muscle memory. Once you have the harness, go ahead and swap out so you have the spg clipped off in the right place, the hoses are laying flat. If you try and secure a standard octo on the right chest d-ring AND the d-ring is where it's supposed to be, it's very inconvenient.
I'd do the bp/w/harness and swap out the hoses. Then get the regs you want (are you sure about Scubapro?) and the can light as the last thing.
