About Terrain Generating

[IamI]

As a player prefer building machines and factories, but not so interesting in battling with enemies,
Every time I start a game, I would try several times to get a island or peninsula, because water is in fact the most safe wall in the game now.

These maps are naturally generated, not being edited.
As 0.13 released, it's not as easy as past to cancel a enemy generating point (Green circles in the snapshots above), that make an island or peninsula map being more important for building players like me.
But in the same time, the terrain generating algorithm is changed. it seems that official doesn't want generating pure island map(That's reasonable), As a result, the possibility of generating peninsula also decreases. I am now tired of trying generating map again and again to wait for a fit.
Yes, I can open the peace mode. But it makes me uncomfortable that there is always enemies in neighbor.
Is there any mods can help? Or if I had to write it myself, any ideas?
P.S. I know the mod Watermaze, but map generated by water maze is too smooth, not natural, seems like the terrain is cut by a kitchen knife. Any better choices?
