Check out:
http://yodasoccer.sourceforge.netwhere you will find a PC version of a remake of Sensible Soccer, complete with source code in PC Blitz Basic.
Although I think we should keep the graphics "exactly" the same as the original sensie (or to have as an option) this shouldn't be too hard to port.
If you have a PC, try the demo, you'll be quite suprised I think.
I started a project a while ago (I start a lot of things but never seem to finish most of them... :-) ) where I coded the sensie menu in an RTG friendly way in C, ripping the 256 colour menu graphics from the PC version, and ripping the original SWOS graphics from the Amiga version.
I'll have a look for what I still have on my HDD
