Really any verb (within reason, i.e. verbs signifying an activity several people may perform together)? Not just certain verbs of movement? Almost all examples I have seen so far seem to be based of forms of ехать or идти. These are the example phrases I found, which I have jotted down:

Пошли домой = Let's go home.
Пошёл работать = пойду работать = I should return to work now.
Перешли мне, пожалуйста, его ещё раз. = Please send it to me once more.

And the single example so far with a different verb:
Начали = Let's begin!
