Personally I doubt you can ever achieve THAT kind of “feeling” for what the crowd once (and the broader kind of DJ you are the harder it gets). I have played 6 day/week residencies for 4-5 months on end at one location. Yet every night would be different.
If you make a mix especially for that night and then trash it, maybe, just maybe that could be ok (as a backup for when you need to pee). If you plan on using the same mix more than once … not good.
And finally, but this is entirely my personal opinion, the entire point to DJ-ing is to create a mood on the night. And I can’t see how you’d do that from the safety of your couch in the week leading up to a gig.
