[texhax] How to get \varnothing working?

I am trying to get the \varnothing character to work in a plain TeX file. I
have read various things that suggest how to do this, but essentially they
all fail the same way: with a "! No room for a new \fam ." message.

It seems like fnts.tex uses up a huge chunk of the available \fam table
(I'm not sure why, in this day and age, internal table sizes aren't
essentially unbounded, but I expect there's a good reason), to the point
where trying to add AMS glyphs fails.

Is there some way to add this one glyph and still use fnts.tex?

And if not, can anyone suggest a way to have both:
1)  access to \varnothing; and
2)  an alternative to fnts.tex that will occupy less table space and stil
allow me easily to change the base font size of text within a document?
