I wouldnt, you already have more fish mass tan I do in my 4 foot 60g tank. also, I dont thin that you will be able to provide enough territory for all of the bottom dwellers. This will stress them and if you wanted to breed them all of the eggs and fry will probably/will be eaten. I say this because when fish like rams and apistograma's(cakatoo's) lay eggs they get territorial and the more they have to defend, the more stressed they get and out of frustration they just eat the eggs.
