I think you will find it's more trouble than it's worth to try to reengineer a horse drawn plow to fit a single point hitch and still have some control of the depth.

I love totally opposing views on whether or not it will be possible....

Most things are "possible".
Many things just aren't worth the effort and costs.
If you have someone to drive while another works the plow it can be done, but I think you'd be better off to get a disk plow you could run by yourself.

This is actually my tractor http://www.tractordata.com/lawn-tractors/000/1/7/175-massey-ferguson-12-attachments.html

When I saw that I thought: "That's not a small tractor"
(I didn't notice the -12)
Here's my Massey Ferguson 175:

Bought some buckwheat today so the first cover crop will go on as soon as the plowing and discing/tilling is done

You know Buckwheat won't tolerate cold don't you?
