MOI to Inkscape to MOI

As Incscape seems not to support the quick an easy AI import from MOI via copy and paste
I would like to ask if someone has found the quickest way to move a shape from MOI to
Incscape, enrich it there with curves created with the amazing Spiro plugin and move all
back to MOI.

PS As I read there seems to be no way ever to license Spiro for MOI - so is Incscape
still the only software to offer this amazing way to easily create perfectly rounded curves ?
