As far as morphs go DAZ did most of the the hard work for you, the EXP system they used for the Gen 4's makes it easier to add channels to a figure, getting the channels from one Gen4 into another just requires you to know which files to copy over, running the correct updater and then loading the 1.2 MB CR2 that DAZ supplied for the figure, the readscript lines in it will do the rest.

The attached pic is a screen shot from DS4.5, it shows I have V4 in the scene (left side) and that I also have Freak 4's morphs in her (right side), as you can see from the textures she's wearing (and yes those are hairy breasts) swapping UV's in DS is childs play, with Poser you have quite a few hoops to jump through.
