Not even up to 10, as base 6 is better.
I saw above that some wish a shifting to base 12, which is better than 10, but it's on the same rank as 6.
If we want to change our number system, as we already have existing bases, why not change for an even more efficient, how about 30, (I don't know if we have enough symbols for base 210).

Dozenal is the best base!!! See page
