Era Level 665 Impossible?

Will preface this by stating I maxed all the marquees on day 1, so I've obtained the maximum number of zerek ability modules possible.

Currently have:
Yoda & Chewie - Level 95
Asajj Ventress (Dark Disciple) - Level 95
Darth Vader (Duel's End) - Level 95
Maul (Hate-Fueled) - Level 95
Stormtrooper Luke - Level 93
Inquisitor Barriss - Level 88
IG-90 - Level 85

I have 45 zerek modules in reserve after finishing today's run of Vader's marquee tiers. I need 280 to take Luke to 95, 840 to take Barriss to 95, and 1,050 to take IG-90 to 95. That means I need 2,125 more zereks to finish taking each of the era toons to 95 to hit Era level 665.

Vader's marquee is scheduled to run 2 more times, but you can only obtain 320 from tier 7, 210 from tier 6, 295 from tier 5, and 210 from tier 4 per day. That comes out to 2,070 total.

How are we intended to get the remaining 55 zerek modules? The way the era rewards are currently set up, this isn't possible to obtain.
