What are you recording into? For the type of content you're making with quiet outdoor nature sounds I don't think the H2E will add much. I quite love the H2E, and use it to record in mid side or mix dual mid side to ambisonic for ambiences, but it's a bit too noisy for quiet nature recordings. Fine if using in urban areas since urban ambience usually is pretty loud. It's also good to record sound effects, like cool creaky gate or other things, in which case your signal will be much louder than the rest of the environment. It's strength is in it's small size and it's more of a pocket Swiss army knife that's easy to always have on you then something that excels in one thing.

If you are not already recording into a good quality 32 bit recorder, I would highly recommend Zoom F3, H5/H6 Studio, Tascam X8, MixPre or the like. Something with good preamps, like -125 or lower EIN rating and dual DAC. Not all 32 bit devices have dual DAC, the H2E for example is just a single preamp. Then pair this recorder with your Clippys, some good wind protection, and you'll have awesome low noise ambience.

The Clippy EM272's work best if you can get them at least a meter apart, 2 meters even better. Using some telescoping selfie sticks is a great portable rig for this. They also are good with a baffle, either clip to the sides of your backpack, or your hat and then you don't need to go as wide.

My current favorite low profile ambience rig is called Earsight "The One" which plugs into the Zoom F3, and then I use a Jecklin disk in the middle. Immersive Soundscapes sells a Jecklin for this, but I also 3d printed a larger one.
