Well, as for that...it is all taste.
The F/A-18 even though not my taste for its FM, has a very very decent 3D outside and inside and even the FM is very sophisticated...wrong but sophisticated.
So, yes, you can have fun with jets in IL-2 and you should be able to add all modded jets manually to CUP.
You can do the same to vp's modpack, only requires forum reading.
You need the engine Mod 2.7 and one of the latest updates
The Common Utils mod
Rest as for modded jet readme.
Modding an IL-2 install is very rarely getting your dedicated taste delivered as one package, usually you have to add a few mods of your liking.
This forum is huge and you will find instructions and mods en masse.
Have fun
Cheers
