Arguably the biggest reason for the lack of other holographic weapon sights on the market is the extreme difficulty and complexity that goes into making the holographic system - it's nowhere near... Like... Not even in the same zip code as easy as making a simple reflex sight with a curved lens and an LED emitter. This is also part of the reason you don't see them being overly inexpensive, relatively speaking to red dots. Everyone is entitled to their own opinion of course and we'd never downplay the extensive pedigree of EOT in civilian, military and law enforcement use, but there are a number of improvements made upon the holographic system as a whole (It's not even remotely similar aside from creating a hologram) in the UH-1 that have been many years in the making. Not the least of which include significantly less thermal drift, significantly less parallax, more than double the battery life and a more inherently durable construction.

The idea of a small holographic sight more closely spec'd (In size) to a micro red dot is an interesting one. Probably the biggest allure to the holographic sights is the fact that you are not looking through any lenses at all as you look through the sight - only "Windows". Thus, you can make the sight picture as large as you want, without experiencing significant image distortion. This is the reason micro red dots are "Micro" and the bigger the sight picture/FOV through a red dot gets, the bigger and longer the overall unit has to get at the same time. Even then, you're still looking through a curved parabolic lens and experiencing some image distortion that sacrifices the "Heads up Display" type feel of a holographic sight. Making a holographic sight smaller wouldn't hurt anything - it would still be a completely distortion-free image, but you're not really taking advantage anymore of the fact that you can get a bigger and clearer sight picture than a red dot.

There's the part about people with astigmatisms, and while holographics tend to have a better track record with those folks' eyes, they not completely "Immune" to the negative effects of an astigmatism. Factor in the fact that any holographic sight is still going to be relatively more expensive than a prism scope, which you can already get about as small as a micro red dot, with a similar reticle and with absolutely no issue at all with an astigmatism, that part starts to become somewhat of a moot point.

Not impossible but one would certainly need to develop an entirely new holographic system which isn't exactly a quick or simple task. You should check out some time how a hologram is made - it's actually quite incredible. From there if something were made, it's basically the typical product development cycle of creating prototypes, testing, tweaking, prototypes, testing, tweaking, until it's just right. All hence the reason another poster previously mentioned "There's nothing on the immediate horizon" Time will tell!
