It is a bit unclear what you are trying to do. But to get to the object, 
you need a path to it. Just use the first objectManager that they both 
share as the root.

    <dtml-var "path.to.some.object.index_html()">

To give it a new context, you can pass it "this()" as an argument ( a 
"mapping dictionary")

    <dtml-var "path.to.some.object.index_html(this())">

You can even hand it some named parameters also:

    <dtml-var "path.to.some.object.index_html(this(), title_or_id='Some 
New Title')">

The values in the dtml page will be looked up in this order:

named parameters -> mapping dictionary -> the objects original context
