Why the f* would Sturgeon be happy with a majority Tory Government?! She said herself she wanted to keep the Tories out and would be happy to work with Labour in order to do so.
SNP policies are left of Labour and while they may differ, they have much more in common than SNP v the Tories.
I'm pretty sure NS and the rest of her party are appalled by and planning to fight many Tory policies, including massive welfare cuts, scrapping the Human Rights Act, reducing the rights of employees and unions, etc etc.
