I ride a fat seat with around 3 inch of seat post, I love being able to seat, and i don't want to break my ass on a slim.
Also i ride this seat height because i had save me many many times while doing manuals; at the loopout time, I just seat on and my front wheel goes down instead of jump running after the bike while holding grips which could be really scary and dangerous while doing high speed manuals on the road.
Fat seats can be annoying while slamming, I had try and i often hit the seat with legs / foots / ankle...
For the increase bar height, good idea, I'm 6'1 like you, i was riding a 21" frame and had moving my bar (8,75") higher and higher with a high rise stem and the good amount of spacers, moving the bar higher can be cool for the back but at a time you need to also increase the top tube lenght or you'll be crisped by another way.
Moving to a 21.5" frame was the best decision ever to me.
To try the "feel" of a longer tube, push your bar forward to have a more roomy bike, but the handling will become more quick because of more weight over the front axle, also easier to nose manualling, some people like that, i personnaly don't.
So it will not reproduce the feel of a 21.5" tube, but the room you can win with it.
I know the frame wasn't in your questions but it may help you in the future.
