The difference between the standard and sport is night and day having started with the standard and changed them. I can only liken the standard to more like hard sofas and I found them very unsupportive, but ironically fairly comfortable on long motorway journeys. The sports are a much narrower seat and of course much deeper base and side supports, so the trade is they hold you well but can be more restrictive on longer journeys. For larger people this in itself could be a problem, but for me and Mrs CJ they fit the job perfectly
Incedetally though the seats use the same frame they are made very differently. While the base of the standard fits over the posts for the back the sports sits entirely inside, being some 4" narrower. For this reason I don't think you'd readily convert a standard to sport, but of course could increase support.
On the heating element IIRC you can buy those as retrofit items.
