Curious about this as it seems to me that delaying the tweeter output would be the same as setting the tweeter back on the baffle to preserve the time domain...but I'm not sure hence this question.
Thanks for any replies.

Yes. You can also time delay a straight elements in an array to make it behave like it is physically curved.
No. Every off-axial measurement will have different phase summation/spl. The difference can be for better or worse, depending on z-axis distance and off-axis angle, both horizontal and vertical.
Acoustic point source position on z-axis is hard to define, it is different for cones vs. domes! Eyes wil deceive! Old guidelines tell to find the position of magnets, which has some relevance only for compression horns. The issue gets more difficult when crossover frequency goes up and crossover "order" gets higher.
Coaxial mid-tweeter is superior in this regard, but not perfect because typically crossover is in range when wavelength is shorter than cone diameter and cone no longer behaves as point source.
