If the intent is LFO, it seems like it might be easier to do this with
a microcontroller like a PIC or something. You need to write some
code but you gain flexibility and the electronics (basically the MCU
and maybe a couple of serial DACs) will be less involved compared with
a bunch of counters and associated logic.
And what you really want - have a few digits of 7 segment displays to
show the selected phase separation and make it continuously variable
in 1 degree steps. Maybe have 8 outputs that are selectable - so you
could choose 8 phases of one waveform or 2 sets (4 phases of two
different waveforms) or 4 sets (2 phases of 4 waveforms) - something
like that.
