Kate England would have to play Dana the dancer/dance teacher only. She might get to plumb the depths of Dana's humanity and flesh out the Mom-Sis-Dana triangle of misunderstandings, petty slights, and loathing.
If we assume the Lioness started banging freelance back in 1996, when she says her world turned to shit (no dates since 1996!) she would have been 42 or so. She may have been escorting in her early 40s. Kate might pull that off. For early noughts Dana - I think her first porn scenes are from 2003 or so- when she would have been in her late 40s, we would definitely need Bea Arthur for the part.
