Nearer than the Remans? I don't think so.
The Borg are scary (in part) because they're relentless and growing, per Picard's little "we fall back" speech. The Remans are clowns and failures. Their one shot at power and they backed the wrong horse (Shinzon), their lives were likely worst after the events of Nemesis than before.
As horror creatures go, it extremely hard to take the Remans seriously.
