Is it possible to collect 100% of Spirits, and level them all to 99+?

I know you can trade them in for CORES to get some others, and presumably still get some (or all?) of them back even when you do this...

I'm wondering with enough time and effort, is it possible to get every single one and level/upgrade them, or is the system designed to sacrifice some for others?

I am sure you could eventually, I would just expect it to take a very...VERY...long time.

 

[Idon]

Obviously it'd be.

But like... there's gotta be better ways to spend your time.

 

[Kholdstare]

Well, it's better way to spend your time than doing drugs.

 

[FFSMB]

I honestly can't think of a better way to spend my time; at least my gaming time...I'm really exciting about this mode.

 

[Ctreasure0124]

I mean sure why not

 

[FFSMB]

Apparently trading in cores destroys them, so I'm wondering if it's possible some cannot be acquired more than once., if that isn't the case....sounds like it will take FOREVER.

This is trophy collectothon 2.0 right here. I’m not up for the challenge, but I would be impressed with whoever has the time to do that.
