Linking Meshes from Teen to Adult

[SkeleBear]

Is there a tutorial somewhere which explains how to link two otherwise-unrelated meshes together from one age to the next?

Example:
I'd like to be able to create a skintone that would link Warlokk's Teen-D-Cup Mesh with Warlokk's (Adult) Classic Pinup Mesh or one of his Adult D-Cup Meshes (I realize this may have already been done once or twice). What I'm looking to do is be able to select a skintone that will ultimately result in a more realistic and natural growth of the Sim, basically so that I don't have flat-chested teens sprouting into juggy adults :happy8:

Any help is appreciated.
