Alterations to an existing image

Hello, attached is an image of cereal box - the image, character, etc are no longer in use. I am creating a promotional t-shirt and would like to do a take-off on the image. The main title, the word Trix (in green) should be changed to read Tryx (a change in spelling), remove the purple square that says fruity shapes, and if possible, the random cereal bits above the character. Also, add the phrase: these Tryx are NOT for kids.......your creativity on placement, etc is most welcome. Finally, can you dilute or wash-out the outer edges of the cereal box making it more appealing on a t-shirt.

I have provided an alternate image just in case it proves to be significantly easier, however, it does not have the desired corporate logo in the upper-left corner.

Thank you!
