How can I wrap each element in a slot?

I wrote a component (Component B) that accepts list of custom components via slot like this

// Component A
<div class="component-a">
  ...
  <component-b>
    <component-x></component-x>
    <component-y></component-y>
  </component-b>
  ...
</div>

and I want to wrap component x and y in other component, such as li tag.

// Output
...
<ul>
  <li><component-x></component-x></li>
  <li><component-y></component-y></li>
</ul>
...

I tried with

// Component B
<div class="component-b">
  <ul>
    <li v-for="item in $slots.default">
      <component :is="item"></component>
    </li>
  </ul>
</div>

It doesn't work. The item is VNode object and it can't render with component tag. Is there any solution to solve this problem?

Edit: My wrapping component is not li tag, it's a custom component with specified props that I set it in component B. If I wrap them from component A, I need to write the custom component and its props repeatedly.

Edit2: Render function maybe solve this problem, but I'm looking for solution with html template (single file component).
