The late Stan Lee who was part of Marvel Comics made cameos from live action to animation and the products weren't worse because he appeared/voice acted in them. Lewdgazer could make inhuman sound effects like seagulls squawking or laser beams being fired.
As for adding spoken dialogue for videos under 40 seconds, I see the pro's and con's. A pro can be the use of "dirty talk" like in live action porn, especially from the female. A negative is there's too much dialogue that it's off putting. Another thing is worth considering is animating the mouth for speaking as it means more work for Lewdgazer. Of course Lewdgazer could easily use the "inner voice" as spoken dialogue; unless Lewdgazer wants to suffer.
