I really don't understand, why you should have 1.2 volts drop on say 10A bridge and waste 12W, when you can have 0.6V drop and waste only 6 watts?
Here are some thoughts:
What applications do you think would benefit from this and at what cost?
If you are building an unregulated battery charger or something like that, then you'd save a little power at the cost of increased price--but would it matter?
If you are building a regulated linear supply, you end up dissipating power in the regulator anyway...
If you want a more efficient supply you would use switching as opposed to linear.
Also. comparing an 8A bridge rectifier with Schottkys rated for 5X more current is apples to oranges--a larger bridge rectifer will have somewhat lower Vf at currents that are a fraction of what it is rated for.
Producing a whole line of Schottky bridges would result in a huge number of part numbers because of the variety of reverse voltages. You can't just sell a 600PIV part that covers almost all applications like you can with silicon diodes.
Lastly, you can easily build up a bridge out of two parts--a CA and a CC dual packaged Schottky--at a reasonable cost and with better thermal characteristics than a packaged bridge. In your case, find the mate for this one and I think you have a good solution for $4 (sqp) in parts. So the answer here is that there likely isn't really much demand for large or TH Schottky bridges.

Hornby Electronic contains other products and information you need, so please check it out.
if your aim is to use for mains rectification, you must be sure that each such diode the Vr is compatible to the voltage you apply.
secondly , if you try to use a bridge at smps etc where the AC output is at =higher frequency, check whether the capacitance of these diodes comes on your way.
at Higher voltages, there , perhaps , no need to use schottky diodes ass additional voltage drop may not be an issue.
If you are proposing at say 3.3V or lower power supplies of very large current, many people do use mosfets to reduce the on resistance of the rectifying element.
each mosfet would be triggered by the voltage level at the gate by a small extra winding.
try to google for the actual schematic .
