What if Roshan's pit becomes something more? instead of Roshan spawning again' and again

What if they bring some entities from the DotA 2 inside the Roshan’s pit? each time you defeat one of these monsters or god or any lesser being. This pit will spawn another, and more fierce some being like Maelrawn - for example shown in Kunkka’s lore I think or maybe it was Silthbreaker. But I think if they do this it will be original and more fun instead of Roshan spawning again’ and again.

Which makes it kinda boring I know it can break the lore but seasons wise you can upgrade the lore by putting something like Roshan no longer has to suffer more for his sin Ancients have take over more parts of the world of the ancients and now even God’s bends their will to these primordial beings.
