Go to the Ryanair website, make a dummy booking on the dates/route you are now interested in, and you can see exactly what Ryanair will charge a "new" customer making a brand new booking on these flights.
As I presented above - this problem is solved. As always, agent on live chat has no clue and Ryanair just adds automatically check-in bags and priority for new booking during flight change.
Thanks for help so far. Now I just need to call them and ask if my current baggage & priority is transferred to new booking during flight change or they just discard it and I need to buy it once more for new flight...
