Depending on the requirements of your road fit and what size SC you have, it may be doable without looking like a freak.
For instance, I'm a fairly average dude and here is how it would pan out for me:
my road bike coordinates are as follows:
~380, ~550 (~10cm stem, and 80mm reach bars)
My tri bike coordinates are:
But both are in essence, "slammed." And my road bike, I ride with a classic bend bar, so switching to a flat transition shallower bar would get me another 1cm in height to my hoods position and maintain my drops position.
So I would need to find an addition 3.5cm height and reduce reach by 1.5cm. 9cm stem on shorter/shallower bars - not bad for a guy on the smaller size, which I am. 3.5cm height is where you really have the potential for a not so attractive looking bike, maybe try a 0 degree stem, or -4; but you'll still need some spacers.
I'll need a 90mm stem I think - the steerer stub makes the calcs a bit more problematic, so there is going to be some trial and error (ie cheapish stems from ebay) involved. If 90mm with 6 degree rise works, a Tririg Sigma will get slapped on to make this truly cable-stealth.
