I'd be more concerned about the potential for getting needlessly near to Vmc for the day.
Simple fix .. if the runway chart gives a speed schedule for a higher weight, it isn't going to present a major problem on the day ? Let's not be ridiculous but I would certainly like to have a suitable crosswind pad, based on the typical numbers, so that the speed schedule used is known to be above the book Vmcg numbers.
Keep in mind that the published speed schedules usually are based on nil crosswind (7 kt for the older BCAR manuals) .. the actual Vmcg will go up by, typically, 0.5kt/kt (fuselage engine twins) and a bit over 1kt/kt crosswind for quads .. if the wind happens to be from the wrong side when the noise quits on one.
