Lalibits and the perfect morphs do not really work together and will cause pokethrough issues because both of them try to correct the same thing and this will exaggerate the corrections. It is much more as just the hip morphs

There is a limit to the number of morphs in V4. Unless the products make their own custome channels, they may overwrite eachother. This may be the case with lalibits and the other morph sets.

Depending on your OS you may have only 2GB available and you will run out of memory pretty quickly. 2 V4 figures with clothing may already be a problem
