Another Spa Panel breaker question

Well I'm fixing to climb up in the attic and run the wire for my 50 amp plug right after Christmas (6/3 so no worries). I've been eyeballing Eaton 50 amp GFCI breakers. They run $100-150 dollars. Now, I can get a Eaton 50 amp spa panel for $50 dollars. My main breaker panel has plenty of room so here's the question.

Can I just pull the breaker out of the Spa panel and use it in my current panel?

I've eyeballed them at HD and they look identical. Now, I wasn't able to pull the breaker out and check the model number but I'm betting they are the same. My breaker panel and current are all Eaton.

If they are the same breaker, I see no concern to pull it from the spa panel and install it into the main. Better IMO to have it in the main anyway.

That's what I thought. It can never hurt to ask.

Eaton(Cutler-Hammer) have two unique panel boards; BR & CH.
You'll need to match the SPA breaker to the style.
