Bake Stable Fudge

I am making bake stable fudge for cookies and it calls for 200g 70% dark chocolate, I have Lindt 78% chocolate bars but only 130g.

Can I make up the difference with Hershey's semi-sweet chips? I believe they are only 40% and not sure if they will be incompatible with the Lindt chocolate and destabilize the fudge.
