It was already mentioned that Bova is 3 and Ravel is 2. As for Ingvild definitely worth more than 1, so they can't add her without taking off someone from the team. She might join later as a backup in case something happens to Grayfia or apart of Ravel's strategy. A lot of people think that Rias or Issei can just joined the winning team, but I feel that won't happen because of pride or disrespect. Given their personality I feel like it's like saying we didn't give it everything we had because win or lose I can just join the winner. They put their own teams together knowing that they may face each other and how do you think it reflects Issei as King  joining other teams after his so called lost. It's the same if Rias lost too as a King and as a lover.
