Sorry, but this isn't really acceptable like a hack, it's more like an ASM showoff. You didn't edit anything but added this little feature.
This could fit better maybe as a sprite/patch (?), but I noticed that it's a bit glitchy (Mario died a lot of times because hitting the wall etc.). So better if you test it a bit more before submitting it to anywhere.
