Will polyurethane glue (gorilla, etc.) work ok for bent wood laminations or do I need to stick with plastic resin or epoxy glue?

Yes - but be prepared for a "Chinese Fire Drill" as the stuff foams and drips and generally creates a mess.
On a recent job I finally gave up my frustration and started laughing as the floor was full of drips (the piece overlapped my glue-up table), my clamps got sticky, my gloves got sticky, my shoes got sticky - all while the clock was ticking.
In the end the items got cleaned up and the lamination turned out just fine with no "creep".

Polyurethane is messy and will show if you don't remove it all prior to finishing. I've only had one failure of Polyurathane glue and that was when I didn't wet the surface that goes against the glue. That joint failed, and I had to redo the job. I went to my supplier and to the folks at woodweb adhesives forum and they both told me to wet the surface that would go against the glue.
I really dislike Poly glue. I only use it for outdoor cabinetry, and I am considering switching to TiteBond 3. The stuff is messy, ugly, and I tend to use it up a lot faster. At the end of the day my hands are black, no I don't wear gloves. On something like the broad surfaces encountered when laminating it would be more messy than normal. I know that Poly has good elasticity when cured, but that could mean creep in a lamination. I don't know that from experience, just a guess. I would use epoxy for outdoor laminations.
Pardon my spelling,

Make sure that your next project is beyond your skill and requires tools you don't have. You won't regret it.
