Do you have an email address? I'll send you my ideas for the rest of the Mega Man 4, Mega Man 5, and 6 Wily Wars style songs. While not perfect, I'm sure you can improve on them. I'm sure some Mega Man 4 songs were covered already.
No thank you. It's not from me being dismissive or anything, I just don't know how to translate any of your suggestions to tracks. I have no idea how to apply music theory, let alone understanding major/minor keys. I apologize.
