Short answer is yes.
However, it will take some work on your part to get it done. What I do to modify a theme (I'm the opposite as I ONLY like the icons themed) is I put the theme on my Windows 7 computer. I use iFunbox to do this, though there are other ways. The address on your device for themes is var/stash/Themes
The, on my computer, I go through every folder of the theme and delete the stuff I don't want (this is the [tedious] "work" part). Once you have finished, put the modified theme back on your phone (in the same place - I usually rename it).
Then, go to Winterboard, activate your new theme, respring and enjoy.
Again, I do this with every theme I buy because I just want the pretty icons. It IS a lot of work but worth it to get the effect you want.
Good luck.
