Here is what I want to do, please let me know if this is OK.
-I have a $1k IB voucher
-I want to use points for Business class on the flight from Bos-Mad(only 32k points each)
-Plan to book round trip Bos-Mad from Dec 9th-16th, cost is under $1k for 2 using the voucher
So,use points over, voucher back. The problem is a one way booking is much more than $1k.
Can I book a round trip and not show up for the Bos-Mad leg but do so for the return leg?
End result would be 64K points for Business class on way over and using voucher on way back.
Any problems with this?

edit looks like this is a no go for all airlines. please delete thread
