Does every detail need to be spelled out in order for one passage to relate to another? Do they have to each have all the same details in order to be about the same event? No, of course not. So, what you're doing here is known as an argument from silence. Just because that detail is not specified there does not mean that it can't happen at that time.
Jesus taught that all of the dead will be resurrected at the same general hour/time.
John 5:28 Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, 29 And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
How do you reconcile this passage with your view? If the sheep and goats do not include people who are resurrected from the dead then when do you think what Jesus talked about in John 5:28-29 will happen? It talks about all dead people being resurrected at generally the same hour/time and then either rewarded or condemned. When else will that happen if not when Jesus comes to judge all people at His second coming as depicted in Matthew 25:31-46?
And what did you mean when you said "Jews will be judged at the GWT"? All people will be judged there.
