I do not think this can be done with LaTeX 2e without Deep Meddling and possibly not at all.
The package documentation is pretty clear: the package involves rewriting internal LaTeX routines controlling output (page 2 section 2.2). This is why it requires two columns as a class feature or option (footnote 7 page 2). It therefore seems unlikely that you can mix the rewritten routines with regular routines in a single document without significant re-engineering, although LaTeX 3 promises greater flexibility (page 2 section 2.2).
If you are prepared to risk Deep Meddling - something which cannot be recommended - then you could - if you really insisted and genuinely pay no heed to the consequences - attempt something along the following sorely misguided lines.
Just remember that when your document breaks, you get to keep every one of the teeny-weeny itsty-bitsy pieces.
Note that I set
\relax to allow compilation. I have no idea what this does so this is obviously an extremely foolish thing to do. Did I mention that this approach cannot possibly be recommended?
The result produces footnotes which look like this in the first part of the document:
and like this in the second:
which is significantly better than I expected, frankly.
