[Space] Adapting to long days and other implications of a generated system - Page 3

I've been working on a world to use as a setting for an upcoming campaign, and I decided that I would work out the world's entire system with the Space rules.

I had decided that I wanted a double world, with two standard garden worlds orbiting each other, but all other details of the system I determined randomly.

Random generation came up with the following:
My world-pair consists of two worlds, which I'll call A and B.
A is practically a twin of earth (a result which I predetermined), except that it has only 50% hydrographics and it has a Warm (304K) climate.
B is a less-dense world, but with almost the same diameter; as a result, is has lower gravity (0.76 G), a Very Thin atmosphere and a Chilly climate (267K). It is also 80% ocean.

These worlds orbit each other closely, at a distance of only about 127000 km, and are tidelocked to each other, giving them a 98-hour day.

These worlds orbit a G6 star, with a luminosity of 0.61, and so have quite a short year (270 days, 66 local days).

In addition, the primary star has a relatively close compion, an M0 star (luminosity 0.091), which orbits at a distance of 6 AU (12.4yrs to orbit). Its orbit, however, has an excentricity of .5, so its distance to the primary star varies from 3 AU to 9 AU.

I want to use this as a setting for a fairly standard fantasy setting, but would like to see if the system as it stands offers any opportunities for interesting color or unanticipated difficulties. Specifically:

I intend there to be an established TL3+magic civilisation on planet A, which is the primary campaign world. Would it be feasible for this civilisation to have set up colonies on world B (a powerful empire in the past would have had the resource to teleport and/or set up gates to there)? I figure that their greatest problem would be the low air-pressure, but how well could a TL3 society be able to manage under those conditions?

Also, how hard would it be for normal humans to adapt to the 98-hour (four-DAY) days on such a world? Humans would have arrived on this world from Earth in a Banestormish way about 2000 years ago.
How well would humans arriving from modern Earth be able to adapt?

Since planet B is about 10x the diameter of the full moon as seen from A, I would think that in those parts of the world where B was visible, nights would be much brighter, but I don't know to which extent.

Another source of light would be the companion star. I don't know that much about astronomy, so I don't know how much difference it would make in the level of light during the day or night.

Are there any other interesting implications of this setting that I've missed?

Thanks in advance,

Indigar
