Markus yeah this might not be worth the effort but I guess I'll leave that up to you to decide.
Essentially I would start with the top card, duplicate it, then duplicate the card-1 class, rename it to card-5 and give it a z-index of 4. To make it look different, my suggestion would be to actually do a negative rotation of -3 deg on the card, so it just continues out the fanning of the cards. The real pain comes in the interactions, you would have to apply the same cadence in the interactions as the other cards as well, but you'll want to put card-5, card-6, card-7 etc above card-1. Its just easier to add on top of the deck than to try to change the whole deck to account for extra cards, if that makes sense.
I am also not sure you would be able to do 10 cards in this section because then you'd have a ton of scrolling, so you'll have to account for the viewport height setting on layout417_component class to probably be over double the size (from 300vh to 600vh), which again is a lot of scrolling.
Here is a read-only to a project where I've started the process of duplicating, so you get the idea. I didn't make any changes to the interactions but if you still want to move forward with it, I can certainly help with that as well but again, its going to be pretty complicated.
