I've replaced the LIP with a few useful utilities - alternatively the matrix mixer, links and a wmd/ssf toolbox would also work well
personally I would consider either an extra row almost exclusively for utilities and maybe a bit more modulation - a function generator or 2 perhaps or reducing the size of some of the modules by replacing with similar smaller modules - the mixer and the attenuator perhaps seem a little on the large size as does the sequencer (which could go into a control skiff)
a decent selection of utilities will massively open up the capabilities of your synthesizer, they are the inexpensive dull polish that makes the expensive shiny modules actually shine and stops them tarnishing

Utility modules are the dull polish that makes the shiny modules actually shine!!!
