That would result in a 2 am sunrise time, which most definitely would disrupt sleeping patterns.
To be more precise, what I was wishing for was 60* sun angle and sunrise/set at 05:00 and 19:00, respectively. I don't think anybody would want a 02:00 sunrise!
(And can I have a link to the site you got those tables from? )

Peak midsummer Sun angle is easy to work out: 90-(your latitude-23.5). For the Arctic Circle this gives 47 degrees; 90- (66.5-23.5). 45 degrees would be 68.5 latitude.
Similarly for winter (lowest midday Sun angle) it's (66.5-your latitude), so 16.5 degrees at 50 latitude (This also gives the maximum declination below the horizon in midsummer, less than 18 and it's twilight all night).
And at the equinoxes it's just (90-your latitude): the sun is at declination 0 degrees. So 40 degrees at 50 latitude, 30 at 60, 23.5 at the polar circles.
In an ideal world (for me), you could get long days with a very high sun. The peak sun angle here in June is about 87.5 degrees but days are only about 13 hours long, I would prefer days that are about 20-22 hours long. This would be possible on a planet with a higher axial tilt I'm assuming.
45° max is too little, it's a low and yellow light like what high latitudes get year-round anyway. It drops below 45° in mid-August here and that's when it no longer feels like summer. Around 50° with civil daylight through the night would be optimal. Endless light is a big part of summer for me, pitch black nights in June would feel weird.
