just my Opinion for
no 1, i think it couldn't be done, because in order to make their trips to the outside world safe is to update the "Big Daddy store" first, the skin module needs to be upgraded from changing the skin color to "hyper realistic artificial skin" or better, it's been used in many film, by film maker nowadays in RL, got the idea right? the game itself is in the future setting so.... yeah, it should be possible. then in order to support the theory, it needs to be a new location like a clothing store that also sell accessories, the bot need something to wear before go outside and the rest is depend on the Dev. team.
no 2, it's already done, remember the fist time anon tell the bot to do some dish washing?, i think what it needs is the actual "action(s)" of the bot when it do the chores, then the rest is depend on the Dev. team, probably could add friking action when the bot do some chores.
no 3, the answer probably depends on the player choice(when Dr. Blau's asked how about MC's feeling of certain issue he has)
no 4, i don't know about this, i think, from the begining of the game, the status of the bot is as a "frik bot" that only have 1 purpose "to ensure owners satisfaction" (i guess), and with the improvement/update it downloaded, it enhances the capability. but i could be wrong, maybe in the future there'll be the choice not to "violate" or "exploit" the bot for the mc satisfaction or main story line, and probably more choice what to do to the bot and it's future in the begining.
no 5, well, i think what you mean is 'the bot being more submissive' when the camera rolling, and use it's capability to give more pleasure to the mc. but as it is a bot and the story tells 'the bot have artificial intelligent and more touch sensitive sensor than a human in it's body and probably can download any personality it wants' the bot could just have any and/or every fetish it wants in command or by itself.
well, that's it from me. hope nobody get offended by this
