Adding separate ofTextures into one?

Hey there! Long time lurker, first time poster
I've been messing around for quite some time with openFrameworks, but now I've run into something I don't know how to solve...
I've got several ofTextures which I want to combine into one big texture but I'm at a loss.
I've got a number of camera's hooked up which take pictures at intervals and the idea is to combine these pictures into a sort of collage on which I can then apply effects or use it as a texture on an object and whatnot.

I've been using ofPixels inside a separate thread to store the images from ofVideoGrabber. In my .cpp I load that into ofTextures like so: Tex0.loadData(thread.pixels0);

Is there a way to combine these ofTextures? Or do I need to use offbo and not oftexture? (I don't see a way to do this loadData from ofPixels into ofFbo..?
(and I can't use fbo inside the thread if I understand correctly since I should keep all openGL stuff in the main thread)

Looking forward to hear how you experts would handle it!
