Thanks for the comments, everyone! Glad this silly little experiment is bringing a few smiles to faces!

Now to respond to some individuals:
JediKnight760071, alas, no, I have not read
Triple Zero yet. Perhaps at some point when I no longer have graduate school breathing down my neck, I'll be able to!
CHEWIE, awww, you're so nice! I aim to please. Looking forward to seeing what ou will think of the photocomic thingie that these four are going in!

Clone Commander, thanks for reminding me what that other head was! I remembered the AT-TE one but couldn't remember the other. All the heads except Scorch's are casts, as it turns out -- more on that below.
Both Clone Commander and Jedijaybird: Oh yes, the Bail figure is pretty tall, isn't he, compared to the troopers? Well, let's see... perhaps they've padded their boots for this ball so as to look more impressive to the ladies? Or some such?

In any case, they're not too outrageously tall in comparison to the ladies who are going to attend the ball (who are mainly just temporary spare-parts-swap customs). Here's a comparison shot with a few of them:

And now, Darth Nirvana...
That's a very interesting concept there- I like it. The sashes are nice and the paint apps are very smooth and flawless. Although, in that pic, Fixer kinda looks like he's kinda retarded...must be the Tank Gunner head. Anyway, these are great, simple and very effective.
Yes, the Clone Currently Playing Fixer definitely has kind of a stupefied look on his face in that photo. I'm mainly to blame for that, since his head is a cast of a Tank Gunner head which I painted myself and which ended up with kind of big eye. In fact, all of those heads except the one on the Clone Currently Playing Scorch -- which is just a plain ol' Tank Gunner head -- are casts, made by the excellent Glassman6 and repainted by myself. Here are some close-ups of the faces:

It's embarrassingly clear who's painted and who's not!

The eyes are the hardest part and took multiple tries on all of them -- still working on perfecting that.
Thanks again for the excellent input, everyone! Much appreciated!
