I'm planning to port as much as I can, so far I got Normandy SR1 and SR2, Turian frigate, Destiny Ascension, Alliance Dreadnaught and mass relay tho it will require some work to look at least half as good as in ME (it will not be animated - no rotating rings)
I'm planning to also port Turian fighter, Alliance fighter, Geth Cruiser and troop transport and of course Sovereign
