Welcome to Geekhack!
The K70 has indeed got a non-standard layout, which will make it difficult to find suitable replacement keycap sets. The Pok3r, however, has a standard layout, as well as being a fantastic keyboard (if you can live without dedicated function keys, arrow keys, and a numeric keypad.
There are a few Indian members, although one of our most active, MOZ, moved to South Africa, if I remember correctly. I'm not sure if there are enough of you to form your own local group, or to arrange country-specific group buys, but that would be the case for most countries.
If you wanted to see what interest there is, a good place to start is to organise a meetup, see how many turn up, and go from there.
