Midwest Express: yes, but only when they get better terms.
NWA: big NO. No money and the new RJs (Embraer 170-195 and 728/928/X28JET offer more than the B717)
Hawaiian/Aloha: only when they get their merger approved.
China Eastern: No, not a third narrow-body type. More likely the A318 or B737-600.
Aliatlia: No, A318/319 fleet mix plus some large RJs. But no money.
Aeromexico: Could be, but first CINTRA has to sort things out.
Olympic Aviation: NO GO. Olympic has other priorities at the moment: survival.
Aserca: Only when they find the money.
Seems like a slow year for the B717-200.
