My dream is that the San Francisco Centre mall would be transformed into a huge place dedicated to having fun: restaurants, bars, gaming centers, roller skating, play spaces, live music and so on.

Seems tough. The Ikea Saluhall is not far and since we live nearby we walk by[0] and it makes sense that that location lost many of its food places. There just isn't enough foot traffic. Alternative locations are much more popular. Stonestown is a much more popular mall for non-adults just because it's generally safer. For the SF Centre to become something like that it would require enforcement actions that I suspect would be unpopular in the city.

Add in shops, and I think you've just described a mall.
