Remembering how xeno-unfriendly the Imperium really is it wouldnt surprise me if they had ended up fighting the Old Ones. However, Im not certain if the humans could have survived such a confrontation or not. Best bet would be that the Old Ones would have massively decimated the imperial citizens with either immense Krork Armies, or another species specifically tailored to beat the humans.
