Offset issues

Dear Community,

I need some advice from you all. For a start, I have got bundled curve network to offset. Instead of offsetting entire curves, I would like to offset only one curve for each side of the bundled curves. The offset value should be based on its number of bundled curves. So when it is bundled more, offset value is higher and vice versa. Hope that my explanation is clear. Can anyone guide me?
