Installing part of WM6 Kitchen individually as .Cab files ?

[sdruid]

I've already built a rom that I like but couldn't fit everything that I wanted in it and wondering if any of the individual rom components can be converted to .cab files that can be installed separately.
I've had to install some of the components separately because they would fit in the rom that I built but I didn't see a way to convert other components to .cab files that I can also install that way....on my mini-sd card.
The components in question are:

HTC Album and Microsoft Voip among others...

any help would be appreciated....
