I really don't understand your post.
The Senate conducts the trial according to rules predetermined before the trial. So agreements between Schumer and McConnell can be codified as those rules will be voted on by the entire Senate. Right now as the way the rules are written the Chief Justice may on his own issue subpoenas for documents and testimony. However his decisions may be voted on by the entire Senate and therefore overruled by the Senate. But Roberts orders after being handed the gavel may not be appealed to another court. If Bolton gets a subpoena to appear during the impeachment trial, there isn't another option but to appear. Although he might be able to take the 5th. But the Senate could grant him immunity and then he would then really have no choice.
I don't understand your post at all. Please cite the constitutional passages and senate rules that support your claims.
