I think inspiration has to be taken from the TOS movies and AGT to try and match the spirit of TNG when it was first airing. Much like how the TOS movies were set 20 years after the series aired on tv, the same would have to be done with TNG. Much like in AGT, the Ent-D has undergone a retrofit, although maybe make it happen on the interior of the ship instead of the exterior, as well as new uniforms. And set it in the 2390s or even early 2400s. Its believable that Riker would be captain of the Ent-D by that point. And Spoiler: PIC spoilers ahead have Troi, Thad and Kestra by his side too. But ENT does, at the very least, need to fix how the series ended.
