Can i use OpenGL to render to a DynamicTexture?

I’m currently working on implementing a third-party map application/software into UE4 as a local plugin.
This application uses OpenGL to handle all rendring and drawing, more specifically, it creates a OpenGL texture, then uses a buffer to render to the texture.

My question is therefore:
In order to integrate this third-party software with UE4, can i keep the OpenGL rendring, and swop out the texture which is made by OpenGL with a DynamicTexture (UE4 / A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums)? If not, how should i approch implementing this software into UE4?

Thanks for giving me a few minutes of your time. Links and such are much appriciated.
