@Peter: If you're a patient man, you can use the Engrave > Music Symbols dialog to replace many of the symbols Dorico uses with symbols from Inkpen2, and you could do the same for noteheads in Engrave > Notehead Sets. You should probably first do Engrave > Music Fonts and choose Petaluma so you are at least starting from a handwritten appearance, even though Petaluma and Inkpen2 certainly look very different.
