first - yea they are a bit too vast, but it was already said they will be shrunk down a bit
second - i do wonder; what should be the characteristics of the omicrons in terms of RP
vanilla generalizes them as "dangerous and vast" and that is where it ends. now we cannot have them really dangerous ( as in NPCs ) cause players have complained about NPC strength ( that's why they were turned into laughable peashooters ) but other than that, the "devs" have not really acted against the very concept of the region.
in vanilla the order focusses inwards - as to the core worlds and resides in the omicrons because it is an effective hideout
the nomads - well, they are practicly gone in vanilla, and in vanilla they are technologically weak anyway - but no idea what they are about in disco ( or what plans they have about the omicrons )
the zoners just "are". nither in vanilla, nor in disco - they really have any function but being a filler. they do not mine, they do not produce. they really mostly trade for self sufficiency - and they cannot explore space, cause space is not endless in disco - and any other faction can do it.
leaving the BHG core, which was a very one-dimensional faction in disco purely made to fight the order.
last there are the hispanics who also rather focus inwards to the coreworlds.
the omicrons do not have mining, they do not have (worthwile) planets that are terraformed ( which would take centuries anyway by professional corporations like planetform ) - they do not even have anomalies like the one in the badlands.
they have some ooRP stuff like the admin station
but the question is - what exactly do you people expect of the omicrons in terms of playing field. - what should they offer - and who should profit from what they offer.
one big equalizer in the omicrons is that they really offer not much more than "being remote" ( which is a commodity of certain value - just not a very exciting value to RP with - as it is like playing hide and seek and hiding so good that there is almost no chance you can be found )
but if you just want easier pvp - yes, the answer is to shrunk the region down to ppl can "get together more quickly"
