I don't see why not.
However, as I understand it, there are classes that are unhappy about the close proximity of the concrete walls and I really can't see the track management moving barriers and catch fencing now they are in place. The back straight complex is an easy fix but race promoters will need to let drivers know in the ASR's whether or not they are using the old or new track. Unless stated otherwise, I would assume they will use the 'new' layout. In fact the regs for the first HRC meeting, early May, make no reference whatever to the track configuration or the track length.
