You're trying to fix grip position relative to saddle and front axle? Sure,  you can get your grips in the same place relative to various points in different ways with different stems and bars. Andrew could have added headset spacers and stem length. But... Just because your grips  are in the same place relative to some parts of the bike, doesn't mean the handling will be the same. As an easy measurable, the steering arc radius will increase as you increase stem length. Adding headset spacers (stack increase) decreases reach - that Doctahawk is a good visual of this. You can't just offset that with more stem length and arrive at a bicycle that handles the same as it would with a lower stack, and higher bar.  With any of these changes, there's a reasonable box to play in and maintain design characteristics. I'm sure bike manufacturers would love to make one frame, and sell it with different components. And, perhaps one of the biggest challenges in mtb geometry, fit, and design, is that no geo number is an island. They're all related to overall handling; trying to change - or fix - one measurement will have direct impacts on others. As an example - one place I see higher rise bars possibly useful for me is with anglesets - they decrease reach if you're slackening the bike, and making no other changes. So, install angleset, reduce headset spacers to shorten 'stack' and increase reach, then put bar height where it belongs w/ bar rise. Stem can stay similar length thereby not changing steering radius arc much, or ratio of stem length to fork offset. In this scenario, you've also increased wheelbase, fork trail, and dropped bb; no number is an island.
