When Eren transformed multiple times consecutively as per Hanji's experimants, his titan started to get smaller and smaller he also started to drift and lose consciousness and his titan demenaor was that of a regualr titan and when he ejected himself, it was harder to pull him off his titan and was really fused with its skin plus his facial features were scrambled so it is safe to assume that shifters can get absorbed into their titans and turn back dumb regular titans (like they once were before devouring a shifter).
