Consider these two pixel-oval portals:
xx oo x x o o x x o o x x o o x x o o xx oo
They are the same size, and you can easily make a bijective mapping for each of their pixels.
Rotate one two times in 3D space by 90°, and it fits through the other. If you want more wiggle room, make them taller.

Not sure I’m following. If the portals are exactly the same size, and stay that size, then why would you have to connect one point on one to two points on the other?
