This can work, but the test is `eq' rather than `equal' so you have to pass
not just some random "Variables" string, but the very one used in the keymap.

I think easy-menu is the way to go. Tell us what you tried.
Of course, it may also be important to know the context in which you're
doing that: maybe there's a simpler way.

It's definitely not encouraged, but it should mostly be irrelevant, because
it's an internal issue. Normally, either you have the key already (from
read-key-sequence, for example), or you have the menu entry name (in which
case you have to use code such as the one used in easy-menu to scan the
keymap and recover the corresponding key).
