If you do want to minimize menu diving but you're looking for melody I think a nice small step sequencer and a quantizer would go a long way here. You can already use the Pam's for random I think, and you could mix the sequencer, that random from Pam's, and let's say a long running modulated LFO, and then out that into your quantizer. If you got a dual quantizer it'd be even better.

So proposed additions:
Tirana MK2 + Tubbutec uTune
or
Tirana MK2 + Ladik Easy Quantizer + 2HP Tune + Joranalogue Add 2, lots of combination possibilities here.
or
Tirana MK2 + Disting mk4 + Ladik Easy Quantizer, in this configuration you could always use the Disting for other purposes if you don't need 2 distinct melodic lines.

If you got rid of the 2HP Mult that could also add a little more flexibility, and I also think it could be worth swapping out one of Morphogene, Clouds, and Magneto (maybe put one of em in a 4MS pod) which would open up a ton of room for more experimentation in your rack.
