It's still separate assignments. The only difference is wether you throw them into a single meta-assignment. Or a separate one with main + fallbacks.
The problem with such assignment is it's very hard to balance the alternatives to be equal. Reading a book takes quite a bit longer than watching a film or even mini-series. IMO it's perfectly fine for someone blind to watch a film and then make a report on it. But how many healthy people would just go for a film since it's quicker? And reading a book is quite a bit different experience than a film due to much more space for imagination and interpretation in a book.
P.S. calling people with no disabilities „privileged“ is just... wrong. It's not a privilege to have a set of eyes/hands/etc.
