Well, cocaine is a vasoconstrictor in it’s own right, that is it mediates the effect of adrenaline and the anesthetic, so you’ll still have problems with end arteries. Though I guess injecting into a artery/vein, would have rather pleasant “side effects”.
Cocaine seems to avoid much of these problems when used as a local anesthetic but its also hard to acquire in pure form in the US
