NM circuits traversing exterior wall...

I am relocating my main panel from the inside wall of the garage to the outside and need to extend 18 to 20 home run circuits, awg 12 and 14 mostly. Can I do this with 2" conduit going through the exterior wall and into my new Nema 3R main panel or do I have to run each circuit and wire individually? I'll be using a large junction box and lots of wire nuts to extend the circuits. Do I have to switch to UF cable to be able to run it through the exterior wall? My new main panel has plenty of knock outs on the bottom to run them individually, but getting through the wall in a manner that is acceptable to code is my main question.

Thanks in advance!

Are main panels allowed to be on an outside wall?

Exterior mounted panels are common in some areas.

Relocation of the panel is a lot of work for little benefit. What are you trying to accomplish?

I built a bathroom in my garage. Unfortunately, the main electrical panel is now in a bathroom. No bueno...

(Sorry for the additional thread, but I created this one to try and get some help on the one question of traversing the exterior wall.)

I would run a large nipple between the junction box and panel using individual conductors.

The junction box will need to stay accessible.
