Won’t it just be harder for you to animate a smooth turn to the side or the back, because you have to create the rhg again bu this time as a frame by frame turning stickfigure. Not only that but parts like stretching his arms or legs smaller or bigger get harder. Not to mention you’ll easily get more tired quickly if he has that many tentacles.
Don’t forget if you want him to change face expressions you have two option’s:

1- Delete the parts you want to change looks or block it with a segment or something and add you’re created you part of the face.
2- Delete the whole face and add an invisible segment (0 size) to the head where the face should be and then add a new created face.

Also if you want to make the face expression movement smooth you have to created every frame.

This is why I don’t like to detailed RHG’s.
