I just the TRU Gathering at the Nemesis set and did some simple parts swapping with the Soundwaves. I think both look better. Don't know about the blue feet though but still, I like them both a lot better.

 

you make me want those 2 Soundwaves...

 

I was also going to try swapping out the black parts of the first Soundwave with the gray parts of the G1 Soundwave and maybe the blue and gold crystal parts but I haven't tried that yet.

I also did some parts swapping with the white Universe Powerglide with Stormcloud.
