Oh man, what a picky kitten you have! First off, try to relax a bit. Cats will feel your anxiety, so please try to take a deep breath, go out for a walk, watch something funny, meditate for a few minutes, or do whatever to help you take your mind off Crisco's eating for a while, and make time for yourself to decompress a bit from this whole situation.
Ok, so we've figured out Crisco absolutely loves his kibbles. It's expected, honestly. I don't think there are a lot of kitties that don't. But this can be a good thing, because you've now figured out what he LOVES to eat. Go on and crush the kibbles into crumbs, and use that sparingly to sprinkle some on his wet food, perhaps mix some into it if it gets him to eat it all. As long as he eats the wet food/kibble crumb combo within about 30-40 minutes, I think it's fine. Just don't leave it out for hours, and give smaller portions to see if that helps.
I think I remember you have Fortiflora? Though it's not really great ingredients, using it temporarily to get Crisco to eat his wet food can also help. A lot of dry kibbles are sprayed on with animal digest anyway, that's usually the special ingredient to get cats to love dry food so much.
As Skyrun has also mentioned, you could also try adding in different freeze dried meats as toppers or some mixed into his wet food, too. I've used many types, Stella & Chewy's dinners come in big bags which also comes in turkey, duck, and chicken. I use a few dry pebbles and sprinkle them on to G's raw food to help him eat or finish his meal. (He's my picky cat). S&C is pricey, but for a big bag, it lasts a LONG time. Other good brands are from NV, even Orijen makes some freeze dried treats in various mixed proteins. (You may want to avoid their original formulation which contains chicken, I liked the Regional Red and Wild Boar for its ingredients, kitties loved the Boar.) I also keep rotating my cat's food (canned, raw meats, and freeze dried treats) so that prevents boredom. It's not cheap, but I do use these treats sparingly, so you could buy a few small bags to switch it up a bit as well.

Hope this helps some. Remember to take deep breaths, keep positive, relaxed, and not worry too much. I know that's hard to do, so I'm sending extra positive vibes to you both.
Let us know how it goes.
