IMO,

I think it's risky to use any of those with the Hyperstar (besides the IDAS)

the IDAS was especially designed for fast systems

if you want SII, I can only recommend getting an Astronomik MaxFR SII

I may not be remembering if there is a fast FR dual band OIII/SII filter, but if there is, I'm sure someone will point it out

and yes, narrower filters will give you better contrast; the narrower the better

D1/D2 are SIGNIFICANTLY better than C1/C2, however, you will get bandpass shift using them on a hyperstar or rasa…

I'm in bortle 5 and the difference between my d1 and the c1 I used to use is wild.
