They might not get the entry granted, imo it's unlikely the ACO will choice a one-off 2019 IMSA entrant over a full seasonal one, particularly from the ELMS. And there'll plenty of GTE-Pro entries no matter what (probably 16).
Maybe they will enter the Sebring WEC race to convince the selecting committee?
