Welsh Sides in FA Trophy

I think that a good way to help the Welsh League is to have cross border cups between the Welsh League, and big sides from the English Football System.
The Football Association Challenge Trophy also known as the Buildbase Trophy. 
I say invite Welsh sides into the English non league, FA Trophy. 

If all Welsh Premier sides were invited to take part in the trophy. It could really help Welsh football. It would give teams of a very high standard to play against Welsh Premier sides, and would not take anything away from the trophy.
UEFA allow Welsh, English and Irish sides to take part in the Scottish lower division Scottish Challenge Cup. So why not try allowing Welsh sides into the FA Trophy?
It would really help Welsh soccer. It would be fun for English non league sides to test themselves against non English league sides.

Also perhaps 2 Scottish lower division sides could be invited into the trophy such as Queen of the South, Anna, Stranraer, or Ayr United.

It would enable great banter between English, Welsh and Scottish sides.
It would be a real test for all the sides.

Travel -
The early rounds could be regionalised so teams would not have long distances. Welsh sides could play English border sides or even Welsh sides in the non league system,  such as Wrexham FC.
