Yes you can ! In the following example code, I assume that your HomePresenter is a place and extends Presenter, and your MenuPresenter extends PresenterWidget.
In your MainPresenter :

@ContentSlot public static final Type<RevealContentHandler<?>> MAIN_SLOT = new Type<RevealContentHandler<?>>();  
@ContentSlot public static final Type<RevealContentHandler<?>> MENU_SLOT = new Type<RevealContentHandler<?>>();

@Override
protected void onReveal() {
    super.onReveal();
    setInSlot(MENU_SLOT, menuPresenter);
}

In your HomePresenter :

@Override
protected void revealInParent() {
    RevealContentEvent.fire(this, MainPresenter.MAIN_SLOT, this);
}

Then in MainView :

@UiField Panel mainContainer;
@UiField Panel menuContainer;

@Override
public void setInSlot(Object slot, Widget content) {
    if (slot == MainPresenter.MAIN_SLOT) {
        mainContainer.clear();
        mainContainer.add(content);
    } else if (slot == MainPresenter.MENU_SLOT) {
        menuContainer.clear();
        menuContainer.add(content);
    } else {
        super.setInSlot(slot, content);
    }
}
