When it comes to running a workshop, 30 people is a large group. So, let's imagine you somehow managed to cram all of the material into a single half-day workshop, and you run it with large groups of 30 people, twice per day, 7 days per week. To get through our low-balled figure of 600 people, it would still be 9 months! That's 3 months more than you'll likely be employed for, and that's not including any coordination, scheduling, prep-time, write-up time, iteration time or specific actions that come from the workshops themselves.

The ARIA tooltip role is functionally useless and semantically meaningless. The only legitimate use-case for tooltips is to show information that’s already accessibly defined. So tooltips only benefit sighted users, and are therefore presentational.
