Finishing circuits for road events

[bleedToWin]

Durbie Dash discussions, specifically that the "long" route is too easy, got me thinking - could the SA road scene benefit from adopting a finishing circuit in road races for the Elites like we see in many European races?

Durbie Dash does not have options for a 3 x 15km circuit, but one lap of Vissershok + Malanshoogte and back onto Adderley could theoretically work.

Speaking more generally, adding ~50km on a tough circuit for the Elites at the end of a fondo type event would solve two problems IMO.
It would make the racing tougher and more exciting for the racers, while keeping the main event accessible to a wider demographic.
It would enable non-elites to spectate racing at an event where they are also participating.
