Stop there!

Use \definehead to create your own variation of a heading - much more robust. Something like the following (untested):

  \startsetups PlaceSubTitleAndIntro
    % Set font and and style etc for the subtitle here
    \structureuservariable(subtitle)

    % Set font and style etc for the intro text here
    \structureuservariable(intro)
  \stopsetups

  \definehead [MyChapter] [chapter]
  \setuphead [MyChapter]
    [ style={...}, % heading style
      after={\setup{PlaceSubTitleAndIntro}},
    ]

  \starttext
  \startMyChapter[title={Foo}]
    [ subtitle={Bar},
      intro={Some explanation},
    ]
  The text of the chapter
  \stopMyChapter
  \stoptext
