Sure it would.
A loop could check at what angle each of the straight line's anchor points would be in relation to the circles center. Then a new bent/hyperbolic line would be constructed and replace the old one. Not a very big deal, only have to make certain that the old circle and lines are centered above the new circle otherwise the angles wouldn't match.
All this could be put in a separate script that called the function of the hyperbolic script. I can write it for you if you have time to wait a day or two.

hey håkan - thank for the offer!
i would love to wait 2 or 3 days before
i recreate over 500 lines per hand :))

Hi,
I have now made a "straight-2-hyperbolic line converter" for you :-P

Just open the script in Notepad (Windows) or TextEdit (Mac) and there you'll find some very easy instructions on how the script works.

Before and after pics below.

NOTE!
This is ONLY a conversion tool. Too draw more lines you'd have to use the previous script.

Hope it works, cheers!
Håkan

THANK YOU SO MUCH!!
