In Pokemon mystery dungeons GTI can ghost types go through walls?

Question

And is there any side effects to doing so?

Answer 1

No they can't

Unlike previous games ghost-type Pokémon can not walk through walls. But every other movement aspect stays the same such as water-type Pokemon walking over water.

Where's the proof? It doesn't say anything about ghost types on that page you put a link to. And hunger is not there for the majority of GTI
