I'm rocking a 29" inseam and own a Connie 14 and BMW GS-Adventure. I have absolutely no reservations riding any bike, no matter what the seat-height, modified or unmodified.
For my personal bikes, to make them both a little more comfortable for me, I have a Sargent Low Cut for the Connie and BMW Factory Low Seat for the BMW GSA.
The only time I'm conscience of the seat-height when parking (I need to think how I'm gonna get it out) or coming to a stop on uneven ground, especially in off-road situations.
There is no need to completely flat-foot nor have both feet on the ground when at a stop. IMO....the comfort comes from experience, dirt-bike/road-racing background and in all honestly, dropping a bike or two in my lifetime, every single time was a learning experience.
To answer the OP's question, if he want a ADV bike, Connie certainly is not it. Take a look at the Triumph Tiger 800. They offer a factory low-seat that makes it pretty low and narrow. It's a really fantastic bike too. Also, another advice, don't lower the bike via suspension....and if he really really has to, have it done properly so the geometry doesn't get hoses in the process, and the ride quality.
