tbh, it will be very tricky to reproduce them to the point they will really look like the originals. look at the center caps fo example, they have had good alternatives made, but 1st thing people say is "they don't look like the original".
so unless desperate to stay bog standard, then i'd suggest if you wnted trims to do as some others have and modify car wheel covers.
really excellent examples have been shown on here which do the job exceptionally well imo.
but then the wheels themselves with the thin stip and sokes look sprty anyway
