Fifths don't come out even in senary, so it's a disadvantage that'll carry through anyway. For ease of use with binary computers, quaternary has a definite advantage, and would somewhat improve the precision of results returned by the machine (mostly by eliminating conversion errors).
And... yes. We'd just need to change the prefixes. Metre, quadrimetre, hexadecametre, would that the words for prefixes weren't base 10.
Roman numerals are little more than a notation system, though, which is quite efficient when you translate it into sets of counters in a little sandpit. (Plus, Roman numerals are still base 10. Ten Is make an X. Ten Xs make a C. Ten Cs make an M. Symbols for multiples of five are added for convenience. It would, however, be interesting to work out what MCMXLVIIIIIX is.)
Senary has, I think, the greatest finger counting potential; it easily supports subtraction of all possible two-digit numbers. But, it translates badly into anything binary.
