What Puzz3D has said, immediately above, is true. However, you never know until you try.

The last large 2v2 tournament was sponsored by The Home of the Masterless/Kas and was a 1.03 tournament. We had 16 teams, 2 players per team--a total of 32 players. Granted, some didn't show for their games and lost by default, but we did complete the tournament (after about 6 months, lol). We saw the return of some players from the "old days," including Puzz3D and TosaInu (who, incidentally, eliminated Kas and me in 4 very fun games).

Though there are far fewer STW-MP players active now, the tourney you are proposing is 1v1 and only requires 8 players to proceed. You might be able to attract the requisite number, even if you use 1.03. I do think it would be important to develop and test an installer for the stat, make it available for download, and provide support for it. But I've seen your abilities and know that you can do this via your website.

Keep in mind that 1.03 is quite a different baby than 1.02. You may want to play a few (even a lot) of 1.03 games to see if it meets your expectations. One thing for sure--there are far fewer people familiar with it, so it will "level the playing field," so-to-speak. However, If someone who is familiar with its nuances participates (Sasaki, Pao, Puzz, et. al.), the rest will be at a considerable disadvantage against them unless they familiarize themselves with the differences in the stat and practice a whole lot.
