@Anshika, yes that is a good option. Its good for similar looking
templates. Here it will work as reference, that is, you would only be
able to author (in editor) the original form. The form with 'Use an
existing Adaptive Form' option, is displayed in authoring in non-edit
mode. So it will be a little tough to style the form as per the
template, if that is not the case you may use this option.
