Is there a way to create a plan guide for this query?

Question

How can i create a plan guide for this query，suppose i can't change the query text:
USE AdventureWorks2008R2;
GO
SET NOCOUNT ON;
GO
-- query plan statement starts
DECLARE @Group nvarchar(50), @Sales money;
SET @Group = N'North America';
SET @Sales = 2000000;
SET NOCOUNT OFF;
SELECT FirstName, LastName, SalesYTD
FROM Sales.vSalesPerson
WHERE TerritoryGroup = @Group and SalesYTD >= @Sales;
-- query plan statement ends
AdventureWorks2008R2's parameterization option is simple, i want this type of query can reuse plan:
DECLARE @Group nvarchar(50), @Sales money;
SET @Group = N'Other Country';
SET @Sales = 88;
SET NOCOUNT OFF;
SELECT FirstName, LastName, SalesYTD
FROM Sales.vSalesPerson
WHERE TerritoryGroup = @Group and SalesYTD >= @Sales;
I tried many times ,but it didn't work:
declare @xml nvarchar(max) -- the plan i want to reuse
set @xml = (select cast (query_plan as nvarchar(max)) 
from sys.dm_exec_query_plan (0x060006001464570B405D92620200000001000000000000000000000000000000000000000000000000000000))
-- create plan guide 
exec sp_create_plan_guide 
@name ='Test'
,@stmt=N'SELECT FirstName, LastName, SalesYTD
FROM Sales.vSalesPerson
WHERE TerritoryGroup = @Group and SalesYTD >= @Sales;'
,@type =N'sql'
,@params =N'@Group nvarchar(50), @Sales money'
,@hints = @xml;
Thanks.

I guess you don't wanna fire these queries "adhoc" but prepared instead to reuse the plan:
exec sp_executesql N'SELECT FirstName, LastName, SalesYTD FROM Sales.vSalesPerson WHERE TerritoryGroup = @Group and SalesYTD >= @Sales',
N'@Group nvarchar(50), @Sales money', N'Other Country',88
exec sp_executesql N'SELECT FirstName, LastName, SalesYTD FROM Sales.vSalesPerson WHERE TerritoryGroup = @Group and SalesYTD >= @Sales',
N'@Group nvarchar(50), @Sales money', N'North America',2000000
