Your plan leaves very little tolerance for error. In addition to the variables Jeff mentioned, there is bore alignment to the receiver and barrel vibration, both of which can move the point of impact several MOA. If the boresight error is to the left or right, dialing windage to correct it may cause you to loose vertical adjustment range. I like to allow +/-5 MOA for boresight errors, whatever the source.
Zeroing at 200 yds gives you only about 4.3 MOA of grace. If that is not enough to compensate for boresight errors, you may have to hold-off on your reticle to either zero or aim at very long distance, as Jeff suggested. Neither one is a deal breaker, in my opinion.
Other alternatives are to change to a different base (20 or 40 MOA) or shim the base you have and re-bed it (I'm assuming you bed it the first time).
I recommend that you mechanically zero the scope reticle before you zero to determine if there is a large boresight error. That will help you to understand any problems you find later. If there is no boresight error, you will only have to dial 4.3 MOA bullet up to zero.
