Planning support for Ikea Pax hinged doors

Dear Ikea fan community!

I urgently need advice and help from you. The Ikea assemblers are coming to me on Tuesday. I have slightly miscalculated.
Here is my problem or question.
Is it possible to attach 2 units of 50cm with hinged doors to a 150cm Pax carcass with sliding doors? Do the two carcasses have the same depth? I can’t find any answers in the endless expanses of the internet. Please help! Thanks ;)

Hello.
1. Yes.
2. Yes, if you have bought deep cabinets right away
