The team setup looks correct. You will get 3x exp on all since they all are either a referrer or a referee.

under your current plan if the new team hits 60 (early morning math, so accuracy is questionable)

E grants to D -30 levels
D grants to C - 45 levels
C grants to B - 52 levels
B grants to A - 56 levels
A grants Vet 58 levels


or something similar.

Accounts only grant to the account that referred them. You cannot grant beyond 60. you can however get to 99% of a level, then grant all the way to 60 so that the toon is 1% from 61. Ideally, level 1 team to 60, then 1 to 30 to grant to. getting to 30 doesnt take that much effort even questing. That gets 2 full teams of level 60s.
