Copy a sketch in a circular way

Hi,

In the picture below you see a sketch (guide for a loft). I want to copy this sketch to all the corners (see 1, 2 and 3). I thought to use a pattern, but that is not possible it seems. Does anyone know a smart solution, without make a separate sketch for each (1 side can be mirrored though). Or maybe it can be done in the loft feature itself?

Thanks!
