Yes it is feasable to photoread and activate 10 books during the summer.
Sure you can remember that much if you want to. You remember a lot of stuff you learnt in the first 10 years of your life already. So it's possible. Really up to you and no one else.
The best way to find out is try it and see. Have fun with your learning.
