You could easily have 3 or 4 times more fish in your larger tank than you currently have.
I would however flag up an issue with your blue ram. Blue rams like the water hot. Much hotter than the danios and corys like. Personally i wouldnt mix bolivian rams with blue rams because, again their temperature requirements dont overlap. I have tried keeping blue rams in community tanks at typical community tank temperatures and it hasnt been a great success. They are prone to ill health and have shortened lifespans due to the lower water temperature. If you raise the temperature to a suitable one for the ram, same problem with the other fish.
Not sure what to say for the best, as you already have your blue ram and i presume you dont want to rehome it. The best thing to do for the ram is to get her in an environment more suited to it, and stock fish that like water up at 28/29c. Keep the other fish in a tank at 24c with more fish that like that temperature including bolivian rams.
Or set up your tank at 24/25c and just accept the ram will be more prone to ill health some time down the line. To give you some comfort, from my previous trys at keeping blue rams, 1 is still with us and doing good. So its not a guaranteed death sentance, but its not a good idea and i wont do it again.
