Default Can we resize partitions

Ok so recently after breaking my samsung vibrant I was using my nexus one until lo got my one s and I'm wondering if we can resize partitions like I could on the nexus one because I would like to give some of the extra system and cache partition space to sdcard. Because aposp Roms use a little less than half of the system partition and android doesn't use the cache partition hardly at all since 4.0 so we could take 200mb from there and leave cache with 50mb and get an extra close to 1.5gb to either data or sdcard. I personally think it's just a wast of space that could be used for other things. Because I personally will problebly never run sense unless we get a kitkat build of it
