Sure i guess there could be a problem. there will always be some who will not like it. But that is their problem and not yours. Everyone who is on a team in a fellowship should have an opportunity to play. If it were me I would let those who signed up first get the chance. If someone wanted to play but was too late in signing up then too bad. However then I would say whomever played in one tournament should give someone else who didnt play a chance in the next one. Or possibly do a blind draw and rotate the team each tournament so everyone would get a chance that wants one.
