Nov 28, 2023 at 17:11 comment added V. Rogov Your construction always gives rise to a complex manifold $M$ which is a holomorphic principal bundle over $\mathbb{CP}^1$. In particular, the family of complex tori over $\mathbb{CP}^1$ is isotrivial. As Michael suggests, you can take the twistor space, then the family will not be isotrivial, so it does not come from this construction. It would be interesting to ask if there exists a complex structure on $M$ such that $M$ does not fibre over $\mathbb{CP}^1$.
