EK using action surge doesn't seem like a huge problem to me. They are quarter casters, so they have a fairly hard limit on the type of spells they can use, and the action surge itself is a fairly limited resource.
With multiclassing you could give action surge to a sorcerer, but at the cost of 2 levels of spell progression. That is a strong multiclass, but losing that spell progression hurts.
On the other hand, casting two spells per round is something that a sorcerer (or a wizard with haste) could potentially do far more often than once per rest. Keep in mind that the rule is based on experience going back to 3.5 edition D&D where casters just dominated the game once they survived early levels. Cantrip + spell is still strong (remember that firebolt scales with level, you get 2d10 starting at level 5). If you dip a pair of warlock levels you can get eldritch blast with charisma added per hit (so 2d10 + 2 X cha at level 5). Even doing that twice per round (no spell) is pretty strong single target at level 5.
So... my opinion is that they should go with core... and let people mod in 2 spells per round if they want to.
