If only the letters in their initial positions need be different, the tower need not be higher than three tiers:

AGE : EGO : EMO
N L : N L : L U
YAK : DAD : DUD

EGO - the self of an individual person
OLD - having existed for a relatively long time
DAD - father
END - the extreme limit of something
EMO - a type of music ("emotional rock")
OUD - an Arabic stringed musical instrument
DUD - a person or thing that proves ineffectual
ELD - olden days; antiquity
