A conventional station, unlikely. I am not sure if SDAH could theoretically be fitted with two platforms making it equivalent to HWH; but for other stations, heavily unlikely.
A more plausible scenario is something that happens in Tokyo. High speed tracks and suburban tracks both converge onto the same station premises and hence, the station technically, becomes much grander than it actually is. Think, if Delhi Metro's NDLS station and Airport Express line were in NDLS campus itself; then it would also have hit twenty platforms easily. In the decades to...
