So, you're looking at making a Nova?
That means all omni, so your Viper and Rifleman IIC are out, unless you're providing different transport options for your elementals and simply making two teams that aren't necessarily in the same force on paper.
Don't discount the Nova. In fact, its arm-only loads are great for carrying Elementals, because then it's not limiting firepower.
Something else to consider, team roles. You should look at your Star in the same light as any well-rounded RPG team, since you're never sure what you're bound to face. You already have good anti-infantry with the elementals, and mixing up each point's primary weapon isn't a bad idea.
I wouldn't be too afraid of something like a Mad Cat as your heavy anchor, or Mad Dog, as WT suggested. In fact, any of the early invasion omnis are pretty good choices. All clans have access to each one.
And, being omnis, don't be afraid to switch up loads between games, either.
If you're going for particular looks, I can't really help you.
But, if you're looking for teams,
a couple suggestions -
Thor as a mobile sniper and range hitter.
Fenris as a medium with speed.
Ryoken for its potential versatility
Nova for being a nova, and being everywhere.
Puma/Cougar for something light yet versatile, and survivable.
It's easy to go either all wolf or all falcon if you follow the old distribution observations in the original TR 3050.
You could keep things clan agnostic by swapping the Thor for a Mad Cat or Mad Dog and swap out the Cougar/Puma for a Kit Fox. The latter is glass-jawed, but has a solid swing. I thought there was a variant with a Large Pulse laser, but I'm not finding it. That might be the Puma.
When it comes right down to it, if you want anything fancier for the medium and light classes, you'll have to look to later books, of which I'm not all that familiar with.
