How can I copy between two open instances of Excel in VBA?

Question

I want to copy data from one already open instance of Excel to another instance of Excel in VBA. I tried:

Option Explicit
Sub copy_paste()

    Dim destination_sanitized As String
    Dim fs As New FileSystemObject

    destination_sanitized = fs.BuildPath("c:\temp\", "1.xlsx")

    Dim xl As New Excel.Application

    Dim wb As Workbook
    Set wb = xl.Workbooks.Open(Filename:=destination_sanitized)

    Dim r1 As Range
    Dim r2 As Range
    Set r1 = ThisWorkbook.Sheets("hidden").Range("E10:E13")
    Set r2 = wb.Sheets("Sheet1").Range("J20:J23")

    On Error GoTo Cleanup
    r1.Copy r2

Cleanup:
    wb.Close SaveChanges:=False
    Set xl = Nothing
    MsgBox Err.Number & ": " & Err.description


End Sub

I get a "1004" runtime error: Failed to execute copy method of Range class

How to copy data from one already open instance of Excel to another instance of Excel in VBA?

I understand how to do this when they are part of the same instance. In this particular case, I need the two books to be in separate copies. I also need to make a full copy (checking data, formulas, values, formats, etc.), Therefore r2.Value = r1.Value will not be sufficient.

Sub MM()

    Dim varTask As Variant
    Dim XL1 As Application, XL2 As Application
    Dim r1 As Range, r2 As Range
    Dim OtherWB As Workbook
    Dim destination_sanitized As String

    destination_sanitized = CreateObject("Scripting.FileSystemObject").BuildPath("C:\temp\", "1.xlsx")

    With CreateObject("Word.Application")
       If .Tasks.Exists("Microsoft Excel") Then
           For Each varTask In .Tasks
           Debug.Print varTask
                 If InStr(varTask.Name, "Microsoft Excel") = 1 Then
                      If XL1 Is Nothing Then
                        Set XL1 = GetObject(Replace(varTask, "Microsoft Excel - ", "")).Application
                      Else
                        Set XL2 = GetObject(Replace(varTask, "Microsoft Excel - ", "")).Application
                      End If
                 End If
           Next varTask
       End If
       .Quit
    End With

    'Then something like...

    Set r1 = ThisWorkbook.Sheets("hidden").Range("E10:E13")
    Set OtherWB = XL2.Workbooks.Open(destination_sanitized)
    Set r2 = OtherWB.Sheets("Sheet1").Range("J20:J23")
    r1.Copy r2

    'Clear down memory afterwards
    Set r1 = Nothing
    Set r2 = Nothing
    OtherWB.Close False
    Set OtherWB = Nothing
    Set XL1 = Nothing
    XL2.Quit
    Set XL2 = Nothing

End Sub
