Will latex paint dry thoroughly if applied too thickly
Yes it will dry and it will "dry" in a couple days with right temp and air flow controls.

However with the amount that you put on there it could be a long time before the paint actually cures and it may never cure to the point of a good paint job.   Depending on a lot of variables even after it cures the inner paint may become rubbery or even worse it could become chalky and never bind right.
