The thickness will depend on the insulation you want to add and the 'elbow room' you're willing to give up. A full inch would be as much as you'd need, I'd think, but that can encroach into the space more than you might like. I used 1/2 inch with 1/2" closed cell foam panels glued in place in between, with the battens onto that. We gained a lot of room because all that replaced a 2" thick cushion.
As for bending, the strips can be kerf-cut to facilitate that if they are not flexible enough as they are. Kerf cutting also makes keeping them in place as it cures a bit easier..
