As for the effects on detection: it depends on detector details, because it varies with sensor resolution, but a decent rule of thumb is to reduce range by the fourth root of sky brightness, so 10,000 times brighter would be 1/10 detection range (side note: the +24 should really replace the +10 for in plain sight, not add to it).

And how much denser and how much brighter can it reasonably get without upsetting planetary formation, climates, requiring a very specific solar history etc.?
