Can I create a SQL view to show "fake" data - sql

Question

My boss wants me to create a view in SQL to show data that isn't there. Is that possible? Here's what I need:
I need to show our internal currency conversion rate for any sourceCur that = targetCur. We only have this data for the year 2011, period 1. I need it to show all 12 periods for every year from 2011 to 2017. The value will always be the same (1). Here are the columns yearNum, preiodNum, sourceCur, targetCur, convRate.
A simple SELECT statement:
SELECT *
FROM dbo.CurrencyConversionRates
WHERE (sourceCur = targetCur)
The results are:
The value of convRate will always be 1 in this case because the currency is the same. I just need to project the data we have (2011 period 1) to all 12 periods for each year from 2011 to 2017. My boss does not want to add the data into the table, he wants a view.
Is this possible?

WITH future( yearNum , periodNum) AS (

CALENDAR
WHERE CalendarYear BETWEEN 2011 AND YEAR(GETDATE())),
currencies( sourceCur , targetCur) AS (
SELECT DISTINCT

CurrencyConversionRates
WHERE targetCur = sourceCur)
SELECT
f.yearNum ,
f.periodNum ,
c.sourceCur ,
c.targetCur ,
'1' AS conversionRate

CROSS JOIN currencies AS c
ORDER BY
f.yearNum ,
f.periodNum;

Use a numbers CTE:
with CTE as
(
select 1 as NN
union all
select NN +1
where NN < 12
)
, CTE2 as
(
select 2011 + NN as N_Year
from CTE
where NN + 2011 < 2017
)
, CTE3 as
(
select C2.N_Year, C1.NN as N_Month
from CTE2 C2
cross join CTE C1
)
select C3.*, [OTHER STUFF]
from CTE3 C3
left join [Other table] OT
on OT.TheYear = C3.N_Year
and OT.TheMonth = C3.N_Month
