Night time coast to coast in Scotland

Unsure why, but I really fancy trying to do a nighttime C2C from maybe St Andrews to Oban , still very sketchy at the moment but curious what the roads are like (as in suitability) for cycling through the night with a few support vehicles and maybe 5-10 riders? Anyone tried doing this kinda thing around that area?

The only other issue I can think of is the lack of places open for refreshments in the middle of the night. But I guess if you've got support cars you won't be bothered about that.
Drumlin, need to think about lights very carefully so that they last the entire time through the night and as you say the refreshment side would be sorted with the support.
Spoke to a few mates and they sound interested but unsure of through the night so this maybe another idea that never takes off......
