Crazy idea - would it work?

I know it sounds crazy, but stranger things have happened.

Has anyone ever held a magnifying glass in front of an eyepiece and looked through it?

I think your question has been answered. However, I'll offer my observations, if I may.
It is true that the image plane must come into focus on your retina. The optics that you use MUST be able to afford this. That would include the "glasses."
This could present a problem. True focus might occur for you at, say, about 15" to 20" from the binocular's oculars!
Also, considering the cost, you may see about 20% to 35% of the FOV of the binocular, if lucky.
I tried one of a similar device about 10 or 12 years ago. As I recall, I threw them in the can even before I returned home. I was visiting my parents on vacation in West Virginia.
I would suggest/advise not to spend your money. But, if you are into experimenting, then fine. Just my thoughts.

good ones get very pricy
but there is a whole range of hand held monoculars that could work
And here's the Zeiss 3x magnifiers, very expensive for two would add $640 to mutiply any Zeiss binocular 3x.
I've mounted an 8x binocular behind another binocular to increase image scale, just as Henry has done. Could not do it hand held. The previous discussions of supplemental magnification reside in the links to the threads on USAF Chart Resolution Testing. I tried holding a 6x30 finder scope behind a binocular but couldn't hold it steady enough to see clearly. Even behind an 8x binocular, that 6x30 finder is giving 48x.

Anyway, might those glasses, without the B&L booster, work behind the binoculars?
I may have to give it a try, just for grins.
