Don't have the tail wag the dog.
Chose the string height you want at the 12th fret. That will give you how much saddle projection there is at that height. It will also give you the vertical string height from the top to the strings at the bridge. They are what they are. If that gives you the playability you want and sufficient saddle height to have an adequate break angle over the saddle - no buzzing or loss of tone - then you needn't be concerned about the neck angle.
