In terms of transistor count, probably. In terms of chip count and designing
the thing, probably not. You can get 4-bit adders and ALUs in TTL, so going to
a bit-serial machine complicates the registers and the timing logic, and
simplifies the ALU, which can be built from a couple of chips anyway.

If on the other hand you want to build the ALU from simple gates, then it may
be a good idea to go bit-serial.
