I think your biggest obstacle here is that it’s nearly impossible to force someone to eat solid food because they have to voluntarily chew and then voluntarily swallow the food.

If you shove the solid food down their throat, they’ll suffocate before dying of overeating.

If you have pre-chewed food and try to force it down, you’re more likely to drown the person or cause them to choke, depending on the consistency of the food. Every person swallows a different portion size and unless you can get the portion correctly and somehow get them to swallow, only then would you be successful at this.

But that is quite the challenge.

So going to have to say so impossible that it’s unrealistic.
