Here is an alternative for elevation based blending that gives you a ton of control in changing the blends, and allows any number of layers.
Use the gradient ramp map! What many people dont know is that if you right click on the colour flags and select properties, you can actually replace the colours with any kind of map.
Here are the steps I made in my example
1. mapped my elevation with planar mapping in one channel,
2. flip the uvw so it's oriented from top to bottom
3. add in your different colour flags in your gradient ramp map to determine your different levels.
4. add in your textures to each flag on a separate mapping channel, add in additional uvw mapping for said map channel
5. move the flags on the fly to make adjustments!
edit: and if you only want hard line transitions just change the interpolation to solid. <!-- you can change the blend curve here too -->
Obviously the downside is that it can be quite cumbersome once you add in additional gradients ramps for other map channels such as bumps, and reflections. but if you work on it incrementally I think it's manageable
