Indesign duplicate items on master page into another master page doc

I need to import specific layers from a template into lots of documents.  The source template contains 5 layers but I need only the items on layers 2 & 3 to be duplicated or  (paste in place) into Master A-Plates page of the destination documents. The script below indeed works but it is duplicating the items of layers2 &3 on the pages.  I need them to be in the Master page A-Plates of the destination document so that way they are available when a new page is added. 

tell application "Adobe InDesign 2017"
set doc1 to document 1 -- document to copy from 
set doc2 to document 2 -- document to copy to
set allItems to every page item of doc1 whose name of item layer is "Layer2" 
-- layer name to copy from
set pageOne to page 1 of doc2 
-- page to copy to
duplicate allItems to pageOne

set allItems to every page item of doc1 whose name of item layer is "Layer3" 
-- layer name to copy from
set pageOne to page 1 of doc2 
-- page to copy to
duplicate allItems to pageOne
end tell

I modified the script to do the same but on the master page but no luck. Any suggestions?

tell application "Adobe InDesign CC 2017"
	set doc1 to document 1 -- document to copy from 
	set doc2 to document 2 -- document to copy to
	
	set allItems to every item of master page items of doc1 whose name of item layer is "layer2" -- layer name to copy from
	set pageOne to page 1 of doc2 -- page to copy to
	duplicate allItems to pageOne
	
	set allItems to every item of master page items of doc1 whose name of item layer is "layer3" -- layer name to copy from
	set pageOne to page 1 of doc2 -- page to copy to
	duplicate allItems to pageOne
	end tell
