My G/S came with a small Givi A210 screen which looked OK and worked surprisingly well. 'bins or 'works have / had them.
Foot shields are around too, which I fit to the crash bars, are unobtrusive an keep the spray off your boots if you do long runs in the rain.
On my R75/7 I have good quality replica Dunstall Decibell silencers which fitted straight on without even a dent to get over the brake pedal, and work well, and sound and look good . Look similar to some OEM types and cheap enough at around 100 quid the pair.
The Give screen deflects the wind onto your hands of course, a set of black GS style guards can be made to fit and do a decent job of protecting your digits, although I must be going soft as I have just bought myself a set of Venture battery powered heated grips for my birthday.
Not inexpensive, but cheaper than five sets of heated grips for all my bikes and also work OK when I take my little mate for a walk.
I like flattish, wide bars too , nothing too extreme but just seem to improve the look/ stance.
If you are doing a complete repaint you might be able to shorten the mudguards a little - it is amazing how much difference it makes to the looks and is otherwise unnoticeable.
Getting the back a little higher is a subtle way of improving the looks too - I have a pair of fully adjustable TEC shocks which work better than the well worn Konis they replaced, and , set a bit higher, improve the look and the turn in / feel at the front too.
Surprisingly inexpensive, less than rebuilding the Konis.
For me the skill comes in improving looks and function but doing so in a way that people have to ask you what is different and what you have changed.
Plenty of of advice elsewhere about building bastardized frankenbikes which for me do neither.
