Seven Echoes all together is a little too much, given that Becky hasn't been in the game long. I'll give you two of your choice from that list, with the future stipulation that you need to slow down slightly with the rate she's picking them up.

Also, I generally don't approve Echoes quite that far in advance (and with the underground shenanigans still up in the air), so I'd be putting this on hold until we get closer to stuff actually happens.
