The only problem with cross draw and shoulder holsters is that in order to bring the weapon to bear, you have to sweep the area with the muzzle. This puts people in that sweep area at risk should you have an accidental discharge.
Of course proper technique should reduce this risk, but only if sufficient practice is done so that proper technique is from muscle memory and not active thought. Active thought can easily be compromised in the confusion of an actual gun fight.
A holster carried at the 3:00, may temporarily point the muzzle slightly to the rear of the shooter, but still at the ground, and the sweep during the draw is always aimed at the ground, rising toward the intended target.
I hope you are not left handed. If you are, I suspect you will be riding alone a lot if any firearms savvy people notice your holster.
All that aside, I suspect that this cross draw would be comfortable, so long as you have a rather flat front side. I am afraid for me those days have past, and the hammer spur would likely become a real naval irritant.
