Don't know much about the risks. But I expect before it would get dangerous, it would just be uncomfortable/intolerable, digestion wise. General consensus seems to be that drinking oil--esp in the quantities you're talking about--is just buying a ticket to the toilet.
Our bodies typically can't absorb/digest oils that fast, and just try to get rid of them.
Half and half is a good idea. If you don't want to just drink it or heavy (whipping) cream, use it as a substitute for milk, coffee creamer etc. It's a good way to ad fat and calories, but easier to digest.
A more comfortable and effective option might be half and half or cream--it's easier to digest, has plenty of calories, and dairy fat apparently promotes healthier fat distribution (burns visceral and promotes subcutaneous).
