I could see Gustin updating the interior pocket since it wouldn't require that much extra fabric to make it slightly bigger. But, it's unlikely they'd do a complete re-design of the exterior pockets. they run weekly campaigns for their truckers, and if they're being funded each and every time I don't see why they'd change the aesthetics if it's already successful.
if they did release a standard looking Levi's style type3 they'd have to tweak it a little the same way Taylor Stitch tweaked their long haul trucker (which is essentially a Lee 101 Rider clone). Using waxed canvas on their current truckers works but they could probably do some interesting denim type3's. Ciano Farmer has already done a slim fit type3 that's longer in the waist. I'd be interested in something like that - longer waist, interesting selvedge fabrics (like the BlackxGrey twill) and cool stitch details. There's a lot of potential but i'm sure people would scoff at the idea of another type3 trucker when the market is currently flooded with them.
