That's precisely the issue. At the moment the split gaiters involve glueing in an environment with loads of dirt and grease around. It doesn't work at all well. That's the problem that needs solving.
If it can be solved, there's clearly a big time saving (and POSSIBLY a really really large amount of money) to be made.
no glue can do that.
staple, clip, clamp etc. None of those will do a good enough job though.

There's clearly an even bigger time to be saved by jacking the car up and replacing the gaiter, rather than faffing around trying to find an easier way.
I've repaired a car gaiter with super glue and it lasted around 3 years until the car was scrapped. However the split was _very_ small and first cleaned up with squirt of two from spray can of Isopropyl Alcohol.
Superglue sticks many types of rubber fairly well. It's what is used for split CV gaiters, and can also be used to make O rings in cases where the geometry or other constrains mean that a continuous ring cannot be fitted. This is done routinely in some types of rotating plant in power stations.
Puncture repair outfits usually use "rubber solution" which is some type of rubber dissolved in a solvent. The old fashioned contact adhesives are similar. This would probably be the best way to make a lap joint between sheets.
Commercial split CV gaiters have a "butt" joint, but get extra area by having a ridge on one side and a matching groove on the other. I've just used one successfully on an ATV which only does a couple of miles a week. I've never risked them on a car.
That won't work. You need to get the rubber properly clean, but then superglue will work fine.
They tend to be regarded as a temporary fix to get through an MOT, etc. Don't think they were ever thought to be as good as an original replacement.
McNett urethane flexible glue for permanent repairs on wetsuits etc. In middle of repairing mine with it. Not cheap. For example:
