Add screens to HUD on input?

Hi, I am making a game with the idea of multiple viewpoints at once. We are accomplishing this by drawing textures on the HUD. We are able to create 2 at runtime using this code.

AMyHUD::AMyHUD(const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer)
// Set the crosshair texture
static ConstructorHelpers::FObjectFinder<UTexture> CrosshiarTexObj(TEXT("/Game/Material/T_Map1"));

MiniTexture = CrosshiarTexObj.Object;

static ConstructorHelpers::FObjectFinder<UTexture> CrosshiarTexObj2(TEXT("/Game/Material/T_Map3"));

MiniTexture2 = CrosshiarTexObj2.Object;

void AMyHUD::DrawHUD()

float ScreenX = 0;
float ScreenY = 0;
float ScreenW = 0;
float ScreenH = 0;

ScreenW = 300;
ScreenH = 300;
drawTexture(MiniTexture, ScreenX, ScreenY, ScreenW, ScreenH);

ScreenX = 600;
drawTexture(MiniTexture2, ScreenX, ScreenY, ScreenW, ScreenH);


And in the player controller I want to add a camera to the HUD with

InputComponent->BindAction("EKey", IE_Released, this, /*Function to add camera here*/);

Any ideas on how to do this?
We are not committed to using the HUD for our screens, it just happened to be the first thing that worked.
