I don't see anything in Yeo's game that doesn't translate to moving to Prop.
8, 10 and 13 are pretty much all the same position for most teams (us included).
I agree with those suggesting a smaller, roving style lock for next season. May or Kenny would be ideal. The increased speed of the game will suit this style of play I think.
And either Kikau or Martin will likely have to shift into the middle too. Capewell's Origin series was too good to ignore. He'll have a starting spot for sure as long as he's fit.
Assuming that Tetevano moves on, I'd be running out Round 1 as:
8. Yeo
9. Koroisau
10. Fisher-Harris
11. Kikau
12, Capewell
13. Kenny
14. May
15. Martin
16. Leota
17. Leniu
