Is interpolations between mono stroke fonts possible

Im creating a mono stroke font for a XY-plotter (Pen-Plotter). Therefore I need non-closed, open paths.
What I’ve understood so far, is that for creating interpolations, the glyphs have to have a stroke thickness.
Is it possible to draw two different looking mono line fonts and let glyphs app interpolate them?
Let’s say I have a very condensed mono line glyph and a very extended mono line glyph. I want the Glyphs app to create me fonts in between them.
Is this possible?

thanks a lot

For interpolation, open paths are fine. You just can’t write them to a font, interpolated or not.
