You might want to also consider that Epoxy has an initial cure time and final cure time. Sometimes the initial cure may only be 20 minutes but the final cure might be 20 days. Under normal conditions, like in furniture repair, the epoxy would be good enough to work in 24 hours even though the final cure time has not been met yet. A 1/4" thick ply or veneer can be under a lot of stress depending on the curvature. Enough to give some or even break loose before the final cure time and lose your bend.
I agree with Steve that wood glue might be the better choice.
I used to make curved wooden combat shields for a Renaissance Group (SCA). I used 3 layers of 1/4" Luan which is slightly less than 1/4 " each. I would glue two plies together with titebond in a mold of sorts, the next day I would add the 3rd ply, also with titebond. Never had a problem. These shields saw a lot of combat with very large men using very hard rattan swords.
