Dear organizers, the fact that you decided to ask the community for their opinion is certainly a positive step. However, if you significantly change the tournament format, you will need to conduct a new registration process, as it may not suit everyone.
And just for those who aren't good at math:
0 - 000
1 - 001
2 - 010
3 - 011
4 - 100
5 - 101
6 - 110
7 - 111
If the number is higher, then 8 - 1000, and so on.
