Even Gollum had had a hard time getting (eating) some goblins since they rarely go down by the lake... and Bilbo (not yet in the deepest of the deep) was able to walk in the dark for so long without actually meeting a goblin (besides what Sting hinted at)....so maybe rare...

And another point is...

If the dungeon represents only the deepest delvings....then the player should be transported only if he/she reaches the lowest y-level one can reach in minecraft... since Moria is pretty deep, and you say this is the deepest part....

(i know this may be common sense and you may know this already, and i don't want to be rude, but i don't see it in the suggestion yet..) You use the tower to get past bedrock level, that's the plan.
