Question about operating distance of tags

I had a ntag213 tag,the dimension was 45mm*25mm,its operating distance was 4cm.

If I used MIFARE Ultralight C(50pf),MIFARE Plus EV1(70pf),or MIFARE DESFIRE EV2(70pf) instead of ntag213,with the same field strengh and suitable tag antennas,could they have the operating distance of 4cm or more?

In addition,without regard to field strength and tag's antenna geometry,only regard to tag ICs,if the ICs have bigger input capacitance,they could have further operating distance?

Thanks.
