This is definitely not a waste of time. But though building a physical ALU from TTL is feasible, constructing a reasonable amount of memory would be a waste of time and money.
Once you have written the nand2tetris HDL for the hardware, you could translate it to Verilog and burn an FPGA quite easily.
