I like it! I use very similar team instructions but without the higher defensive line because I find that sometimes we end up compressing the space to much between the defence and midfield.
I'm not sure about 2 things. The assymetric formation, but only because I don't like to use formations the AI can't. The other is, why you need your IWB to have strenght? When team loses possession he will come back to the FB position instead of holding the mid, right? I'm asking because I don't have FM24, maybe in the new edition the IWB holds the middle a bit more before going to the FB position.
