Is it okay if i group all the textures of a model into an atlas?

[klius]

Hi there!

I've been working into ripping some 3D models from a PS1 game and by inertia i've started to combine all the loose textures that came with the model into an atlas and remapping the UVs to that 

If i submit those models, would they be rejected because the textures originally came separated? 

Thanks!
