Unreal Engine 4 : Screen Space Widgets

Hello,

I'm trying to render text to be readable in a large world-scale VR environment, just like in Google Earth VR. The best solution I have found was to use Stereo Layer integration of Compositor Layers in Unreal Engine.
The thing is, there is a maximum number of layers the Rift S can render, which I believe is 15.
What's the suggested alternative to render these sort of textures, to be readable in really large distances, just like normal screen space widgets.
Thank you.
