Nope Sweep on both bars might differ 

 

and even if they match then 

 

using the headangle of the bike and the center of the bar at the original or new height you can determine the diff using good ol hypotenuse 

Risers come in different sweeps. And you could fix the reach with a longer or shorter stem.

Costs $$$ and Just Frana gave you the Answer He Knows Whats What (And It wont work anyway )

Obviously it could be done , but it will likely be a once off 29.89mm stem and bar with 30mm is rise but 7.986 degrees of sweep 

 

I was just pointing out that no , a 30 mm riser bar won't have the grips in the exact same place as putting 30mm worth of spacer underneath the stem ( unless headangle is 90.00000 degrees ) 

 

....just covering all bases

No option here is perfect. Remember that the OP is looking at a bike in a shop with a too-short steerer tube. If he wants the handlebar higher he could:

1. Install that dodgy steerer extender from Ali Express

2. Have Droo replace the fork steerer with a longer one.

3. Use a riser bar to get the right height. Admittedly he may have to change the stem length to fix the reach or have to settle with a sweep that is a degree or two off from where the flat bar would be, but rolling the bar a little might solve that problem too (i.e swapping upsweep with backsweep, depending on the bar). No one is sensitive to fractions of a degree in sweep difference. 

To me option 3 is attractive. YMMV.

Option 4: Chat with the bike shop and see if they have (or can order) a new unbuilt bike with an uncut steerer. This is the route I'd go.

winner winner chicken dinner.

If its a brand new bike then you should not be making compromises because of the decision by the bike shop to cut the steerer.

(there are exceptions. like if the deal is on that particular bike in the shop and its a really good deal)

Thank you all for all of your inputs. I have decided to hold for a while on buying the new bike. New bike day still to come though....Really hope.
