My compromise suggestion - and this would also apply to Henry Cavill (and if he should reappear) Tyler Hoechlin is that instead of making the red area trunks, why not simply have an area around the crotch that is coloured red rather than blue? Think the 'Super Powers' action figures from the mid-80s. I know that they were supposed to be trunks and for practical purposes were painted on but still, work with me here.
Before MoS, this redesign floated around the web:

Now, the collar and red sleeve trimming are hideous, and the boots are no improvement, either, but the red pattern around the waist was a nice idea, I think, and I'd like to see this rather than no trunks.
