It turns out that the bollards they want to locally list are not the blue bollards around the station (I personally objected to them getting listed as they are nothing special in my opinion). It turns out the bollards for listing are at the top of the underpass and I agree that preserving these is worthwhile.
We are unlikely to see a 'Victorian-style' station, and conservation area rules are generally not in favour of attempts to build mock-Victorian buildings that usually fail to fit in. However, the station building, WH Smith and other building in the area are regarded as 'negative buildings' that the council would like to see replaced.
The supplimental planning guidelines (2002) for Forest Hill recommend building a new station building and a town square. Funding is always going to be the problem for such projects, but TfL may be more responsive to the idea of building a new station than Southern Railways or Network Rail have been. Most likely any new station would not be Victorian style but a new 21st century station.
