Seeing that alla has the stats for gear generated and adding to item picture vs just a static in game image, I would think it will not be too much trouble for you to add a scaling option to the various gears. So that I can go to a piece of gear and select the lvl I will scale down to with it and it will generate the stats.
I understand the scaling in game is not yet implemented, but it is coming and I imagine there is some things that can or need to be implemented in site as preparation if this was to ever be done.
