Sorry to bear bad tidings, but there isn't, and probably won't be, a 28 pin 1Mbit EPROM equivalent to 23c1024. The mask rom is only feasible because it doesn't need a Vpp pin for programming, and it has only one control pin (OE) besides the 17 address pins. There is the remotest possibility that someone might make the OE- pin double up as Vpp/program enable, but now the 32 pin pack is established, that's unlikely. Looks like you'll need to make an adaptor board, or bend some legs. Dave E.
