It's all good, this is a unique situation. The CRL in its current form is currently approvable with hard parts/soft parts as they exist in the current CRL. That is what your GML will reference with the current pictures and text. It would be the discretion of your GML if they were to use the current CRL and allow any slight modifications that would cater to the Electrostaff Specialist to get it more in line with the video game images; otherwise, you'd need to build it to the current CRL and not the proposed one.
I don't have a timeline for updating this CRL since we'd need a model to update it. I'm not a fan of updating the text but not the model images, therefore we'd need to do both the text and pictures at the same time. We are happy to accept anyone as a model, but there is a lot of work that goes into that with pictures being taken and making sure the armor matches the text and reference images (e.g., could require further modifications, etc.).
