A torch doesn't give 3x3 light. It's a node with "light_source" set to "max-1". The surrounding nodes are illuminated by this lightsource, not just the next 3 nodes.
So brighter isn't possible. You would have to add surrounding transparent lightsources where possible. I used something similar in my mod with all the problems (enforce lighting update to prevent "lost light", not working on ladders)
