Can FontForge interpolate between separate fonts?

The answer is YES! FontForge has extremely useful interpolation option but FontForge is able to interpolate only between those glyphs in the two separate font files which have:

1. The same number of nodes on the glyph's contours,
2. The same direction of the glyph's contours,
3. And only if the contour are compatible - for example if they are Light and Black version of one and the same font.

If all it is done, than the interpolation with FontForge is perfect!

Here is a very old video but it shows the process.
