What do you mean by this? X-Men TAS is basically just a comic style cartoon with the actual comic designs, but we really do not have anything along that lines for DC cartoons and games, except maybe Super Friends. I'm completely open for DCAU figures that don't explode upon using their articulation, but I can't see them being properly "compatible".
If we skew them to be just labelled JLU or something and be comic figures with those overall looks, those designs are 99% of the time just going to be the most evergreen or iconic costume of each respective character and miss what makes that incarnation special. Granted, I'd much rather standard comic style releases of these exact outfits anyways, but I don't see the point in DCAU, etc figures if they're going to be "compatible" in the sense we think of typically.
