More radical would be to put the S5 sensor in it (hell, the body is plenty big enough), include in camera CA processing like the new D300/D3 Nikon's do.
I think in another 5yrs, 'bridge' cameras will become obsolete, or a tiny niche market. Compact PnS will offer enough range and performance, Ricoh's Capilo R6/R7 while not great have 28-200mm lens, and soon there will be a Nikon D30/D20 series that cost the same as the 6000 does now(body only), with newer dSLR 18-250mm 'compact' zooms from Tamron/Pentax adding OIS in the future, bridge cameras will make less, and less sense.
Ever improving compact, pocketable, PnS; combined with lower cost dSLR's will cause the market for bridge cameras to buckle & collapse, IMO
My panasonic fz50 is pretty darn handy when I'm not in the mood for carrying gear and getting sand/dust on the sensor is not a concern. I treat it like a cheap p+s and it treats me like a real photographer. Sure the sensor is a noise generating pixel stuffed p.o.s compared to an slr... but I keep it in good light and have 35-420mm equivalent reach, built in flash with hot shoe, 848 X 480 quicktime movies @ 30fps, all the manual setting options, quick auto focus, flip down swivel lcd panel, two modes of O.I.S. and Leica glass to capture whatever I want in raw format, or 10mp jpeg at 2.5 fps. Beat that in dSLR for less than six hundred bucks! It is only a bridge, though, and I have taken up the L1 for my more serious photographic pursuits.
