Would it be possible to use the nonce patterns in identification of human played maps/blocks giving them priority?
Not really, it will become increasingly hard to discern bots from humans over time anyway.
Would it be possible to increase the complexity of the maps with higher nonce values?
This wouldn't be much different from just limiting the number of maps available, I suspect.
If there is a way to force bots to emulate the way humans play, would that mean safety and survival of the coin?
Yes, but IMO as long as the chain is still hashing and no-one has demonstrated the proposed difficulty time-warp the coin is still safe and surviving, for now.
Though this could change entirely at any moment, I suppose.
