Use this script to extrude curves along multiple curves

by default it uses circles to extrude, you have the power to change the curve type (linear or cubic), the curve sections, the curve radius and the extrusion scale(Taper)

you can also use custom curves ( select your custom made curve and click on the select user curve button)

and finally select the curves you want to extrude along and click the extrude button
hopefully this will proove helpful to you, enjoy :)
