is available in the mathabx
package, but unfortunately, that package also changes the font style.
Can we define \widecheck
by ourselves?

I did not know if it would be this easy, but it turned out so. I took my revised answer at Really wide hat symbol for
\reallywidehat

I changed the final
\stackon
argument from\tmpbox
to\scalebox{-1}{\tmpbox}
.That was it. Here it is:
Best of all, it avoids the use of
mathabx
, which resets a lot of math symbols.
