Highly unlikely. Organ donation must occur within 36 hours at most (depends on the organ/tissue) and preferably immediately after brain death, while the body is on life support (as a lack of oxygenated blood causes tissue death). In the case of "unnatural" or suspicious death (homicides and suicides), an investigation and/or autopsy is required in most places, which makes organ donation impossible. In the case of a liver, it would almost certainly be unusable after a night of being dead. Many doctors also have ethical objections to using the organs of suicide victims (that's encouraging suicide!), though for practical reasons, that's mostly relevant to physician assisted suicides, so that's another issue, even if you manage to CtB in a hospital and stay on life support long enough for organ harvesting to take place.
It is possible to do a living organ donation for some organs, including the liver, which might be worth looking into. You'd lose a good portion of your liver, but if you're sure that's not going to be a long-term problem for you, well...
