Eugene,

if you haven't tried it already, consider this:

Use a cardboard tube of a fairly large diameter and of a length that
is longer than your widest sheet by a good margin.

Tape a canvas, vinyl, or similar flexible but durable fabric so that
if you rolled the tube it would wrap around it . The length of this
fabric should be longer than your longest paper.

Unroll this on a flat table so that the fabric is flat on the table
surface and the tube is attached on one end waiting to be rolled up.

Place your curled up paper so that it is snug up against the beginning
of this fabric (near the tube end). The curled side should be facing
down (against the direction in which the fabric will be rolled).
Slowly, carefully, start rolling the fabric and paper together until
all the paper has disappeared under the fabric.

Depending on the paper, the amount of curl, humidity etc -- you may
have to use a bigger or smaller diameter tube.
You may also have to let the paper sit for more or less time once it's
rolled up.
And you may still have to tweak the curl of the corners.

To control corner curl a safe option is to use the rounded edge of a
table. Preferably an edge with a generous curve - 1" or more inches.
Think of a 1" half round attached to the side of a work surface. 
You sandwich the printing paper between two thin, clean sheets of
ordinary paper and use your palms to run the corners of the sheet over
the rounded edge of the work surface.

Sounds more involved than it is once you get past the first try.

I believe it is a safer and more effective way to uncurl papers than
using a dry mount press at any temperature.
