I actually tried one of these (the G5236T - sparkle silver top) at my Local GAS Station/Gretsch dealer. And I've had LP's, and an Epi LP Standard. Occasionally (when I forget how broke I am at the moment), my mind wanders toward an LP-type guitar Jones. So I tried this out.
Pros vs. the Epi LP? Besides the Bigsby, FWIW to you, and the mini-bucker pups, are 'nice'; if you ever think of upgrading, the size could limit your options vs. regular buckers. It's lighter, for sure, with a chambered body.
Have you considered an Epi LP Ultra? chambered hog body = lighter than an LP Standard.
Cons? Master Vol & Tone some may consider a Pro, particulary, or, if only in the both-pup position, but I find it limiting compared to an LP with V/T per pup that open up a range of tones in the both-pup position, or give you an option to leave one pup a tad louder than the other at the flip of a switch. IMO, a con.
The neck's a hair 1/16") wider than the LP's. That's an either/or. But I s'pose a Pro if your fingers or fingertips are 'chunky'.
Because of the limited vol/tone control, the mini-buckers and the neck, I crossed this off for good off my own wish-list. If I came across an Epi LP or Samick Avion that made me itch, I'd consider scratching it. But this didn't even give me a hive.
