It certainly is possible. As another reply pointed out, you're mixing
Path and Python expressions above, which won't work.

A common technique I use is to define a local reference to widgets
(often to something short like 'w'), and then access the widgets
within that setup::

    <form ... tal:define="w view/widgets">


      <!-- call (render) the firstname widget -->
      <input tal:replace="structure w/firstname" />

    </form>


Anyways, you can use the 'python' or 'nocall' expressions if you want
to get the widget unrendered:

    <div tal:define="w1 python:view.widgets['1']">
      or
    <div tal:define="w1 python:view.widgets.get('1')">
      or
    <div tal:define="w1 nocall:view/widgets/1">
