Let's say that U6 won the U6 vs U7 tournament and U7 Earth was transported to U6. This would mean that everyone but Frieza from Team U7 would be in U6 instead. Who would be on the new U7 team and how would they fare in the ToP? No one outside of Earth got recruited because Beerus and Shin are very incompetent and had no idea what was going on in the rest of the universe. Broly is restricted to his base form since that's all he had before the movie. No Merus since he is a giant question mark.
Imo the team would be:
1. Frieza
2. Moro
3. Broly
4. Saganbo
5. Seventhree
6. Shimorekka
7. Yunba
8. Quoitur
9. Namekian Fusion
10. A Yardratian (probably the one who trained Goku and Vegeta)
This team would actually be very dangerous imo. Golden Frieza is SSB level. Base Broly is SSB level. Seventhree is >= Piccolo and can copy 3 people's abilities for 30 minutes. He could copy some useful abilities, like Magetta's durability, Botamo's damage transfer, Instant Transmission, Piccolo's Namekian abilities, etc. Shimorekka and Yunba are seemingly >= Krillin. Quoitur is a metalman, so he should have great durability, though it's definitely nowhere near close to Magetta's. He's maybe on the same level as Shimorekka and Yunba. The Namekian Fusion could be very powerful, based on Saonel and Pirina, but I don't think that he would be as strong as them since U7 Namekians are almost extinct, so Saonel and Pirina probably fused with much more Namekians. The Yardratian knows many useful tricks that could make him helpful as support. Moro can siphon off the strength of the rest of the ToP fighters, making him very powerful and nerfing everyone else.
