Ever look at Connors and McEnroe hitting balls from the baseline? They create huge angles with very continental grips, Connors more E than Mc's.
You're overthinking the game by a few steps. Allow your skills to catch up with your mind and imagination.
Theory is only applicable if you have the time and inclination, coaching and determination to hit with strong grips.
Watch the grips of DelPo, Soderling, Milos, Isner, Querrey and the taller players. None use strong SW, most use a variation of E grips, usually towards the strong side.
Strong grips take too much out of your body, something taller players don't have an excess of ....endurance and repetition, fetching and direction changes.
