Well, Dilas is one of the miniboss units that are pretty much there to fill the boss slot or slow you down. But Lemia? Maybe, I don't know if her batch will get (If any.) 7*s but well, anything is possible if GUMI really wants people to play thier game. But if you haven't noticed, most of the units getting 7* are either popular or so weak and out of date that they don't stand a chance against 5* units.
