Moto/4x4 trails have existed for a long time, and bikes like the Surron/Talaria would be great on them! But if you mean new moto trails at places that only have hiking and MTB trails, no, probably not. Most managing agencies and volunteers from other user groups have been fighting motos poaching and tearing up trails for decades and their opinion of moto riders are (in my experience) extremely negative. If the Surron guys want to get together and work on access and trail building, more power to them, but from what I see they aren't really interested in doing the work and have a massive uphill battle ahead to build a positive image of themselves if they ever wanted to start.
Certainly possible! Skateboarders did it in the late 90s-2000s. But not easy and wouldn't be fast.
