If you must do such a crazy thing,the suggestion to do it at 45 degrees
sounds the best to me, because you can use standard components and no
fiddling is required with the gerbers. I presume that the fabricator could
rotate the thing, but you'd better check.
Meanwhile, those who point out that you might have a teeny problem finding
someone to make such a creature have given the best advice.
If most of that 110 inches is simply parallel track, you can get flat flex
cable for that. So instead of making one long board, you would make one or
two short ones with flex cable in between. The short board(s) might be
rigid, i.e., cheap and easy to make. If there are devices which must be
located along the length of the board, you might still be able to make flex
circuits of length L connected to each other with flex cable or otherwise,
where L is the largest practical production size.
