yes, and yes.... would they work like a yagi designed for those bands, most
likely not.

Lots of luck

And don't forget that a new gamma match must be calculated. See
http://www.ve3sqb.com/ and search "gamma" on the page for his antenna
design program "Gamma".

Yeah, most of have explored those "ballpark" equations/formulas for
gamma matches. I even translated one from the basic language to C.
In the end, it is "cut and match."

Yes. It depends on how you mean that, though. Either can be 'cut
down' for use on higher frequencies, or 'trapped' and used on lower
ones (so some ridiculous point). If you mean used as a directional
antenna as they work on their design bands, then no, they won't work
that way without that physical modification. There may be some
'directionality' to it, but not like they are supposed to be (that
make sense?). It can work, but not 'well'.

Don't mess up a good 20-meter beam.
And that 40-meter yagi must be huge! If its working, I wouldn't want to mess
with it, either.
You can make a 10-meter beam easy enough.
I could replace my pickup's hemi with a lawn-mower engine, but then how
would I cut the grass?

I guess the old Mosely tribanders were before your time. They worked
well and on 40, 20 and 10 and other antennas on 80, 40, and 20.
