I did exactly this before in an experimental comic I made a long time ago that was...purely for experimenting so I didn't really care what my readers think. Thing is, I was doing it on my own site so I could have the text hidden and you could kind of pop it up if you were interested to see some side-story content since many of my characters were losing their minds and I wanted to kind of give a warning to the reader before it happened. (so it looked like this http://rajillustration.com/avu/page6 but bear in mind the site is super broken and the parallax scrolling I designed no longer works, which is why I am slowly moving it to tapas, but you can see what I was trying to do at least, where I had blocks of text hidden inside of little links.)
Problem is, on tapas, you can't like--neatly organize these blocks of texts into side pages, and so I don't know if readers enjoy it? I'm assuming they just skip it? Like I've only redone a little bit of this particular comic on this site, and I got rid of most of the text portions but in some instances I kept it because it was part of how I wanted the story to be told in the first place https://tapas.io/episode/1509199, you can see where I kept some of the text where I felt like it was necessary, kind of disguising it in one place to be a pamphlet, and then in another place I just slapped text on there like it was an illustrated novel.
Overall, I don't really care about how readers feel about this particular project anyway since it's my experimental baby that I update whenever I feel like, but I'm sure it's pretty jarring, especially since it does change the tone entirely of the comic (which is what I wanted at the time, I wanted most of the text reveals to be much darker than the cute cat stuff on screen). But surprisingly with the text updates I haven't lost any subscribers, which at 4 subscribers is 4 more people than I originally thought would be reading my spooky cat comic.
But I dunno, it depends on your audience. Personally I like to read words, but if you're a younger reader, which is most of the people on tapas, you might have an aversion to paragraphs.
Overall, I think you just have to do what's best for your comic. The nature of webcomics is to be very experimental but Tapas does get in the way of that sometimes because so many people will be viewing with an itty bitty phone and so many people are just here to escape to somewhere comfortable and familiar.
