It shouldn't be a problem. Calling addMethods without arguments simply
iterates over Element.Methods.* (and family) and adds them to
appropriate DOM elements. c.f.:
http://www.prototypejs.org/api/element/addMethods
P.S.
It might make sense to extend Form.Methods instead of
Form.Element.Methods
myForm.getElements().findAll(Form.Element.Methods.isActive)
// vs
myForm.getActiveFields();
