Well the use of CG on a practical way and not for cheap ways of avoiding money spending is an other thing. I like you are using both ways (CG and props). It actually might help with the PT:R thing.
If it can used right (see ANH:R and ESB:R) it can save time of building and animate stuff with the old ways.
Id love to see some alternative takes or even remastered original ones with CG such as millenium falcon straight flybys or light incosistences or even some poor shots such as the falcon flies above the SD surface before it passes from Needa's bridge.
