If one were implementing a slanted baffle design, is it necessary to adjust the mounting of the driver in the baffle to maintain a 90 degree orientation with the horizontal plane? It seems to me keeping the driver oriented with the baffle would result in it being horizontally off-axis to the listener. At least more so than a normal, 90 degree baffle with the upper frequency drivers at ear level.

Well generally that sort of design is used for time alignment of the drivers. That being said most recommend to not do this with a design that was designed in a conventional box. But I have heard the NatP's in this type of enclosure and they still sounded great.- Bottom

On a slanted baffle, the crossover can correct for an upward tilted vertical lobing pattern, depending on the order or slope that is used.
That said, a 90 degree baffle has some limitations if you want to do LR2 slopes, for example. In that situation, you would more than likely need a delay circuit to align the phase of the midrange and tweeter. One advantage of using a sloped baffle is to help align the acoustic centers of the tweeter and midrange, but then you have the off axis response to take into consideration as well- like you mentioned- which then can be corrected electrically in the crossover to point the main lobe at the listener seated position.
A straight 90 degree baffle can be considered a good solution for certain slopes, but not necessarily the best scenario for others. The stepped vertical baffles can help align phase and benefit the user if he/she wants a LR2 slope (like the slanted slope), but it can also introduce more diffraction if felt is not used around the sharp transitions from one baffle section to the next.- Bottom
