[Mix and match style elements?]

I installed xpize yesterday after reading about it on lifehacker, and i love it. Thank you.

I had a small amount of trouble with the install. Xpize kept asking me to restart, but i was able to work around by running from the command line with /ingnoreCondition.

Now a question:

Is it possible to mix elements from different themes?

For example: i want to run the Luna Element black theme with the start menu from the Royale Lite Black theme (Listed as Luna with the metallic color scheme in Display properties).

Thanks
