This might not be too hard?
StaticLoadObject(UTexture2D::StaticClass(), NULL, *(Path))

Looks like that was relying on some external work. Should still be possible, will need to reimplement https://forums.unrealengine.com/development-discussion/blueprint-visual-scripting/4014-39-rama-s-extra-blueprint-nodes-for-you-as-a-plugin-no-c-required?p=321196#post321196

Create new UTexture2D
Set SizeX, SizeY, OriginalSizeX, OriginalSizeY, Format=2
Copy data to .mips.Data (PF_B8G8R8A8), set .mips.ArrayNum and .mips.ArrayMax
???
Profit?

This should be a good library to start with. Looking for a header-only library without too much bloat.
