More resources \ less empty islands (free-form map)

Free form map has around 8 empty islands(big islands), and several islands with half the amount of resources (2x8)

building up my factory i've scaled each island to be a mono-factory, so one island for blue dye, one island for yellow dye etc.
in addition i've scaled my research to 4x full belts of white datashards and x2 full belts of blue datashards
currently i do not have any islands dedicated to creation of bots.
at this point of the game i have finished all bot targets up to hyperbots and need to start working on regular yellow bots.

having scaled my production to these, IMO reasonable, production goals i've found that i have almost completely run out of usable polyrock.
to create a reasonable amount of yellow cores for either science or bot manufacturing i would need to scale down my previous creations

this issue combined with the fact that there are a plenitude of completely empty islands is a bit irritating. if the goal of the free-form map was so that we can build modular and high throughput factories then there are simply not enough resources on the map to effectively do so.
