Spawning Progressive Waves of Monsters to attack a base, some with the ability to destroy blocks.

I'd like to make a more updated version of the Invasion mod (the one where you defend a Nexus) and so is it possible to have a block that you can place down that spawns progressive waves of monsters to come attack it without coding? A few of the monsters would be able to break or place blocks to get to it too. Is this possible without coding? It would be sweet to build an amazing base and then have its defenses actually tested. Thanks!
