A late-1960s ASW conversion for the Daring class

What would a late-1960s ASW conversion of the Daring class look like, and was it considered?

It would likely trade gun armament for Ikara and a helicopter facility, with HMAS Vampire offering clues to plausible alterations, though none was adopted as a standard conversion.

Various Daring conversion ideas were considered, but the intensive ASW rebuild imagined in the question was not carried out. Ikara is the suggested missile system, with a helicopter platform offered more tentatively. Gun armament would be removed as part of that change. Vampire is named as a place to see some alterations relevant to the possibility, although the question's other comparison is unclear and receives no identifiable treatment.
