As long as you can save protein-ligand complexes in any format compatible with maestro (e.g. pdb), Maestro will display this complex. However, it is not possible to transfer docking scores. Because maestro has its own scoring algorithm and will only write the scores according to this algorithm.

If you need to open the docking process that you have performed on another platform in maestro, you can open the complex in the appropriate format in maestro and docking again, you can get the same layout with the score in maestro. However, it is likely that you will see different interactions from the interactions obtained in the docking process you performed on another platform (this is because the interaction distance parameters differ by default in each software, albeit with small differences) and you will obtain a docking score belonging to maestro (the scores will definitely be different and this is due to both the scoring algorithm and the default values of the interaction distances)

As I am using Maestro ACADEMIC version, I can open the complex and inspect it, but cannot generate docking scores.

Is it even possible in ACADEMIC versions?

Frankly, I'm having trouble understanding what you mean. You should be able to do everything in the academic version. If what you mean is that the software you are using is some kind of trial version, there is no way to get a docking score. As I explained above, it is not possible to get a docking score without docking calculation. If you have an academic licence, you will have a docking score by calculating docking.
