The Kop should be safe standing regardless.
The rules are that you have a specific place allocated, and this has to be supposedly even more stringently enforced with increased safety measures, such as CCTV being mandatory etc. Its not a case of just finding a fee spot as you would on a terrace.
Therefore in order to improve atmosphere this would have to be used as an opportunity to coordinate an active/vocal section (in the middle?) and more passive sections (on the sides?). Just allowing everyone to renew their current seats would be a missed opportunity.
With anything like this, it will probably take a coordinated and organised fan group to ensure if/when safe standing is installed, atmosphere is considered. Could this be within your remit
Stand United ?
