You could save the view set at the same scale and then change it to suit in the layout (Drawing Selection Settings>Properties>Drawing Scale) - this will reduce or enlarge the whole view to the preferred scale, which may not be suitable with regards to other text/labels/dimensions which you may want to keep consistent.
I would suggest a better option would be to copy and paste the section/elevation markers to a site plan only layer, adjust sizes of marker to suit required scale and change settings to be linked markers to the original markers.
