This is what I'd do and I don't think it'd cost much. Almost did it when I smashed a fairing a while back.
Keep oem clocks, spray the white back panel black. Get a high quality round single headlight, 7" min or a bit bigger looks good, lots of oem ones on ebay and mount it so it's quite low. Mount clocks in a similar position to standard - could use the standard fairing/speedo bracket but remove/chop off the unneeded bits? Then get a nice looking screen, will cover up the back of the clocks and make it look a lot neater (guess you wouldn't need to spray the clocks if the screen is dark/opaque). Good quality & nice looking mirrors, again oem is usually the best, and the Fazer's lever clamps on the bars have mirrors holes already.
I think the key is to keep it fairly simple but make sure it looks clean and the parts are of good quality.
