This is difficult. You have published the main draw, so in my opinion you should not change it. In Turin I had today's matches counting for the First round of the Main Draw, even though they were Turin's FQR matches, so the problem did not arise.
Elirj70 should be able to play Braunchweig if he leaves Wimbledon today, but as I said, I don't think you should change the draw.
I believe the last time something similar occurred, the manager put the player as lucky loser #1, and I think this would be the fairest solution in your case. However I think you should wait for a more experienced Board member to also comment.
Are you sure that this is the fairest solution? Is it fair to me when I'm the LL#2?
Or the fairest solution would be following the TT Rules?
From the "Tennis Tipping FAQ/Guide":
How to procede during challengers on a Grand Slam's second week?
If the player reaches a GS R16, they are out of qualifying; if they reach GS week 2, that means they are out of the challenger. These tournaments usually have a Tuesday start, so it's possible to play two qualifying rounds on Sunday & Monday. Players who are out of quallies can still be MD alternates or play doubles in these challengers if they don't reach the GS 2nd week.
This is the rule! There's no need to put fairness here...
