To separate or not to separate (Paphiopedilum)

[aramina12]

I will be needing to repot my paph again soon (I thought I could put it off until next year, but a new sprout came up in an area where it won't have room to grow). I know paphs grow an entire new leaf system for every bloom cycle, only ever blooming once from each, but I was wondering if it would still work to separate them? Will new growth come up from older ones, or does it always sprout off of the most recent one?
Regardless, would it be bad to trim away one of the older leaf systems to allow the plant more room?
In total there are three growths which produced flowers and have since finished, plus the new growth which appeared only recently.
