Can I send surfers to a FPA before the sponsor?

Hi all,
Some feedback needed here. I have a certain sponsor who uses CC Bill as a processor. They are my best sponsor by a mile, but there is 1 small problem, the default billing option is for a single month. Looking through my stats for other CC Bill sponsors, there is a much, much higher member retention as they use the recurring option as the default. Now I don't know if that is down to sheer laziness on the cardholders part or not, but I'd like to find out
This particular sponsor has given me a referral code which gives the recurring option first, so I can see what the score is. However, as it jumps straight to the join page, I'm not sure I'd get that many sign ups. What I would like to do, is on the sponsor link send them to a folder with the FPA, and have the code there that takes them to the join page.
That would mean a folder jump, from www.xxx.com/freesite/ to www.xxx.com/fpa/ so that I don't need to have the FPA in every freesite I build for this sponsor.
So basically, is this allowed or frowned upon by LLs? btw the FPA is an exact replica of the sponsors 1st page, it just cuts out the 2nd page and goes straight to the sign-up form.
Thanks for your input.
