These are your morphs, right? Not a doctor's?
If the left in each is how you look now, then it looks like your upper jaw is in the correct position, but your lower isn't. I haven't read the thread so apologies if this was mentioned, but it looks like a case where extracting lower premolars might not be a bad option to get that liner advancement. Since the upper jaw is in the correct place and the lower isn't, this seems the most reasonable way to get the necessary advancement. If you want more support for your upper lip, you might be able to procline the upper incisors to achieve that, but based on the photos I don't see the need for more support. The support as-is looks fine.
