Default gs2 stock rom on screen notifications

I have tried many roms in the past 1 month and have decided that i just like how the stock gs2 firmware looks and feels...
Except one thing,i want the on screen notifications like the one in "carbon" rom
Is it possible somehow to port that to stock firmware?or maybe someone has already did something like that?
And im not talking about the apk's you can find on the internet or in the appstore...i mean a proper port/mod.?
