Well it's not a Merger thats for sure... 
Optical/thermal fusion good enough to replace separate binos and thermal monocular/binocular is still a long way away and may never happen.
HIK tried it with the Gryphon thermal spotter which had an optical channel as well as thermal.
I have one and it's a total disaster
Pulsar notably avoided fusion with their Thermion Duo which has both optical and thermal channels but keeps them separate and does not even try to fuse the two
If you want to overlay a thermal and optical image, then both systems need to have exactly the same field of view so that the images are the same size and can be overlaid
Because of the huge difference in pixel size between optical and thermal sensors and the resultant lens focal lengths and overall size and weight of the device, fusion devices are going to be limited to fairly low magnification - probably not more than around x3 base magnification.
Also, because the sensors cannot be coaxial there will always be an offset (up and down or right and left) between the thermal and optical image so getting one perfectly overlaid on the other is only going to happen at one specific distance
