I'm going to say that it shouldn't be a problem. I've had to do that myself on multiple occasions. I like to submit free sites which promote swinging amateur housewives to the housewife category, but few lists have that category. So, the result is often a single free site with category recips for housewife, amateur, and swingers depending on what fits each list best. Some would argue that it is best if all recips are for the same category, while others would argue that a more chaotic mix of links it best. Truthfully, there is no winning in this game.
