Call me crazy, but would this make a a really easy hopper for an existing JSP mill?

I've been wanting to add a large hopper to my grain mill for some time, and my friend just brought over and left me a large, plastic 5-gallon water bottle that I'm going to use for the hopper itself.

So I already have a JSP mill similar to this one that I've motorized:

What I'm thinking (always trying to be on the inexpensive side), is to get another one of these plastic carboy dryers (I already have one that I use):

And attach it securely to the small hopper that came with the mill already and then put the five gallon water bottle with it's bottom cut off into the carboy dryer and secure it once it's in. I've already tried it with the carboy dryer I have already and it fits perfectly.

Anyway, wanted to pick everyone's brains and see if there were any comments, suggestions, unforseen issues, etc. with this theorized, quick-and-dirty approach of mine... :cross:

Sounds like it would work fine. I built a hopper with some spare wood I had. This isn't mine but it's the same idea.

Should be fine. I use a 5 gallon bucket. Semicircle cardboard inserts funnel it down.
