I pretty much do what you are saying only with side loaded off the shelf bearings instead of building my own. You can see the exploded assembly here of a previous design that is similar to what I am still using. Based on my experiments, play due to this bearing stack is virtually nil. I don't believe it will have an effect on prints. It is definitely a second order effect compared to the torsion of the 16" arms. My new design will hopefully eliminate the need to have torsional stability.
Thanks,
