Considering that's what I did... then yes
I not that much of an expert with graphic programs (& I dont' have 'illustrator' to creat a proper '3D' one ) all I did was paste (& slightly deformed) my LEDS skin graphic to try & fit onto as existing graphic of a card from the first post (the black one was originally a DSTwo card, the white was the iPlayer but THAT had to be resized as well)
Unfortunately on the white card I couldn't get it to fit quite right without deforming the actually GBATemp logo, making it more 'jaggy' so I tried 'cloning' parts to blank out the rest - not doing too good as you can see....
