Penrose conformal diagram of Morris-Thorne wormhole

Consider the classical Morris-Thorne wormhole solution: $$\tag{1} ds^2 = dt^2 - dr^2 - (r^2 + a^2) \,d\Omega^2, $$ where $a$ is a positive constant, $r > 0$ for one asymptoticaly flat spacetime, ...

How (if) can we connect a 2D "throat" piece of a wormhole to two hyperbolic 2D manifolds?

This question wad closed on the mathematics site, as it lacked clarity. So I try my luck here. My question is cosmology-inspired. Imagine two 2D hyperbolic manifolds. I connect them by a manifold like ...
