"Distance 2 squares means you can't reach other piece from yours, starting from any square of your piece, jumping to adjacent square (not diagonal), within 2 jumps."
As I understand it, around this W piece, the squares marked X would not be allowed
on the first move of other colors:

Is that right?
Can you post some pictures to show what you mean of moves that allowed, and not allowed?
If you have a physical (plastic) game set, you could put some pieces and take photos
(please make them small when posting). You might add some notes to the pictures,
as we have done in the http://pentolla.com/beginner/
Or you can take a screen shot and mark squares, like I did above.
You also said
and see if it become popular.
To be honest, I don't think it will.
This is a very conservative group when it comes to change.
NO variant has become popular to any extent, except Freestyle, and that only
around the time of the tournament in January/February.
Duplicate has some fans, but I think most players don't play it much, some not at all.[Numbers in the following paragraph have been corrected (twice) from the original posting]
Overall, in 2016, about 14% of all C2 games were Duplicate, and nearly half of those (41%)
were games between just one pair of players, and another player accounted for around a fifth
of them (21%)!
In other words, well over half (62%) of the Duplicate games involved just 3 players.
All other Duplicate games comprised just 5.5% of all the C2 games. (Not counting Tollie games.)
I don't think it would be worth it.
However, if you perhaps have some friends you can try this out with using a physical set,
it might be interesting to see how games turn out,
or if you can get some other players to support it, I wouldn't rule it out.
A *much* simpler variation, with perhaps the same results, or close to it,
would be to have alternative starting squares for C2, along the lines of DUO,
or perhaps with some randomness thrown in.
Bernard Tavitian once suggested that for games with short timers,
starting C2 Duo-style, some distance from the corners would be appropriate.
What do you think about those ideas?
