I remember seeing a few type-S in a production based series awhile back on tv, so ur not the first to do it... but anything can be achieved, weather its DC5R or DC5S, both in my eyes are equal when it comes to production based series, they both use similar engines, and chassis, if ur gonna strip the car for a cage, fia approved seats, harness etc etc, than either one is fine imo

What many fail to see that most production based series dont allow for much mods, if anything tires, suspension, safety harness/cage/seat and few more other things.... , so those who say do this an that, u dont have much understanding for production based series, this aint no unlimited, unrestricted time attack series, but a proper "race" with laps and opponents on the track, not some 3 lap based series where who can get the fastest time....
