Thanks, this is good input! Im totally clueless when it come to road/gravle bikes, so I maximized size thinking i could always replace the stem etc later on. Since I have to learn this new type of bike i guess that making too eratic changes in start wont make huge impact (except avoiding soar hands and back for too long reach). I will follow your example here 
I would definitely get an additional 0mm offset seatpost if I were you, it's only 35$. Even with separate bar and stem you still route the brake hoses through the stem internally so swapping up the stem is a pain in the butt. You will have to detach the brakes, remove handlebar tape, then reconnect everything and hope you don't have to bleed the system again. Also those spacers might not work with a regular aftermarket stem so you might have to source another stem from VB if necessary. Swapping the seatpost on the other hand takes 5 minutes if you need to shorten your position
