Should I double a hamburger buns recipe I like or should I make it twice?

I made jushua weismans hamburger buns.l and I really liked them, They tasted great. Only problem, it's only for 6 buns.

So I can make it twice, or double the Recipe.

I never done that before, are there any drawbacks to doing that, will the buns be as airy and fluffy as they were? does it change anything?

I mean the initial dough ball will be twice the size, twice the weight, do any of these things change the outcome comparing it to the results I got for the original batch?

Love to hear your input!
