there is no acetoxy in psilocin, you are thinking of psilacetin (although to be fair it is sometimes called O-Acetylpsilocin).
psilocin has a hydroxy chain.
i don't know if either if these can be converted to DMT, but if they can it would probably require a bit more than the average kitchen chemist has access to (though it is entirely possible i am wrong, i am not really chemistry-saavy).
