I probably did the calculations[1] wrong but the value I'm getting for the apparent magnitude of 55 Cancri B at 1000 AU with an absolute magnitude of 12.66[2] is about -3.9121 which, if located in our Solar system, would be bright enough to see in daylight, despite being almost 35 times as distant as Pluto is to the Sun.

Still, it won't look like 'two suns in the sky', but more like Venus.
Definitely. It would look like a pretty damn bright star, but not like a second Sun.
