Incompatible glyph. Different shape same letter in 2 weights

I’m creating a font with 3 weights. In my design, the bold “g” in simpler than in regular version. Is there any way to do except in interpolation in this one letter? I like my complex regular and thin “g” but the same complex bold “g” looks weird. Should I change it in design or I could solve it in Glyphs somehow? I don’t know if this is possible but it was the first idea that came to my mind.

Hi, tried this?

not yet, Thanks. I’m checking it.
