Hi Bernhard,
that sounds interesting - what will it be able to do?
About the name:
Please read the Inkscape trademark policy carefully first:
https://inkscape.org/en/about/trademark-policy/Then contact the Software Freedom Conservancy or the Inkscape Board about the naming.
I'm not sure if this is allowed by Inkscape's trademark policy, but I am not a lawyer and therefore you should ask there.
If you just do it without asking, it might be seen as a trademark violation (and even with asking, they just might tell you that you need to choose a different name).
If I wanted to change the name in the code, then I would look into the pot file, and then into the file that it mentions:
#: ../inkscape.desktop.in.h:1
msgid "Inkscape"
msgstr ""
and change the message there (I didn't test this, might as well be the wrong place, but that's what I would try).
Regards,
Moini
