Hi!
Your problem is somwhat very usual...
I think your regulator is enough..
the only thing you do are improving the quality of heatsink and built in colling fan..thats all...
try to use aluminum bars with inch thick....if that is wanted to have....

"The µA78L05AI is characterized for operation over the virtual junction temperature range of –40°C to 125°C .."

Try to get samples from TI ..
