I’ve been with UE since the start of UE4, I want to add some information to this even though you want to do things differently than I do 
, probably you know this already:
In UE structures are passed by reference. Structures are going to be loaded into memory, but they are tiny and can use soft pointers as properties.
I love async loading. Just for info I share a post on how to do this for others:
I fully agree with @PinoDFTGames , There is no way to ignore UE its systems / limitations and use 100% of it. It’s not wrong to test and try everything, learn. I personally rewrote many of my plugins multiple times in the first years as I hated (and still hate) ways UE forces me to write my code but not adapting to UE will bite you at some point.
