Questions on reselling a Pistol

If I purchase a 2 pistol Package deal from an individual and follow the law on Transferring is there an issue with turning around and reselling one of them to someone else?
I am not suggesting that I have a 2nd buyer lined up prior to making the 1st purchase which I believe could violate question 11a on the 4473 form (Are you the Actual transferee/buyer of the firearm listed on this form?)

Example:
I purchase a M&P 9 and a M&P 45 even though I am only interested in M&P 9 because the seller wants to sell as a package and it is a good deal. After a week or 2 I decide I really don't like or need the M&P45.
Any issue with selling it?

It is unlikely this situation would occur because one can always use another pistol but just wanted to see if this was allowed.

Thanks for any advice.
