In my opinion only two temps are important, whatever the size of enclosure; (daytime) the coolest ambient @ approx 24c (75f) then the surface temp at the basking site @ between 40 to 45c+ (100 to 110f+). That range would allow the dragon to function optimally. During the nighttime I personally wouldn`t go below 19c (68f), though they experience lower in the wild.
As far as the relationships of the different familes are concerned, it matters not how long ago they diverged, the Iguanids are now thought to be closely related to the Varanids and Heloderms (plus snakes).

Just to add, I know of beardies being kept with and utilizing Varanid temperatures.
