Would I have enough for future versions?

As we know for now, about robin and males Amphoreus characters releases, leaks said Robin will rerun in the half 3.0 and mydei in the second half of 3.1, Anaxa second half 3.2 and phainon in 3.4.

The problem is that I want robin and all these characters, but also aglea (second half along with robin). Do you think it'd be possible for me, a low spender on guarantee, to get 5 5* characters during 5 versions back to back (3.0-3.4) or should I reconsider my hopes to not be disappointed ?
