In the "If you can do it with Lego" department, Warner Bros. is developing a feature film based on Funko figures through its Warner Animation Group, according to Deadline.  Teddy Newton, who has an Oscar nomination for directing Best Animated Short and has worked in visual development and character design on numerous animated features, is writing the story, and Mark Dindal (Garfield, Chicken Little, The Emperor’s New Groove) is attached as director.

Funko acquired its own animation studio back in 2017 (see "Funko Acquires Animation Studio"), and has been producing short videos tied to its product line.  Those could certainly serve as proof of concept; a Toy Story 4 Funko Trailer released in May has nearly eight million views on YouTube.
