I was going to suggest that. My understanding is you get 1 object basically w/ transposer. However, I just did about 10 replicated V3's dressed up fairly easily. I have heard of issues w/ David before so there could be some issue there. The obj thing is also an option. I did observe some interesting mem usages tho. This is on windows tho.

From 251M to 294M opening Cararra
322M w/ sunset indoor scene
Nude V3 w/ hair obj  to 798M
Nude Native( 3 hair items) to 934M
This file (native) w/ 1 v3 to 1150 then when rendering I don't think it went over 1175M
You lose a few megs sometimes if you don't unload Carrara so it isn't exact, but still informational.

No need to think outside the box....
    Just make it invisible.
