My thought is this. Contact reputable surgeons and see if there is anything they can do for you.
It does not sound like you are missing on sensation. My labia don't do a lot for me. Of course they feel, but sexually they are not that important. The sensitivity you have sounds very like mine and I don't think you are missing out on sensitivity. In fact you orgasm a heck of a lot more easier than I do. The sensitivity at the top of the vagina is probably your prostate, I like that too.
So sensitivity side sounds good. Depth is not necessarily a problem. With diligent dialation you might be able to gain a little more depth. But for comparison I have a germen friend with 4 inches of depth and she fucks a ton of guys and they don't know any better. So in that sense what you have can be functional. But if it bothers you you could get one of the colon segment things (though I personally think you can work with what you got to everyones satisfaction, but the option is there)
Cosmetically it sounds like you are not too happy. They can definitely fix some of the things - like the corposa cavernosa can be fixed. That is a not uncommon problem. The urethra ending is another not uncommon problem and entirely fixable (I have that too, and plan a little revision at some stage) . I'm not sure they can reconstruct labia minora, but they might be able to tidy up some of the scaring, and your clit.
So my advise is start contacting surgeons, asking them if you could get a consult, send some photos, and save your monies.
