Yup. At 60Hz you'll hear it vibrating.
Techniques like that are normally rather used with the volume than with
the frequency, so for example you can fake 5-Bit quality samples with the
TIAs 4-Bit volume register by dividing each 5-Bit sample in two 4-Bit
samples and feeding them to the TIA twice as fast as the 5-Bit
sample-speed.
For example
5-Bit value = 23 ( /2 = 11.5)
Will result in
4-Bit val 1 = 11
4-Bit val 1 = 12
(Hm... Isn't that called "oversampling"? :-))
