This 18-300mme kit can fit in a lunchbox, and I can choose primes or the 14-42 for the wide range!
While I find the Samyang 7.5mm fisheye appealing (as I did with the G7) the bargain BCL9 is a 9mm f/8 fisheye that will stand in just fine for most applications. I had figured on 7.5/14/20/30 as the primal set but I've had a soft spot for the 17/2.8 for several years, so its return makes the 12mm a better fit.
On the Pentax side the kit has slipped away. I still have the 10-17 fisheye which hopefully will find a new home soon. The micro4:3 replacement set has taken most of the Pentax funds so taxes and medical bills still await - but some improvement has taken place with the gear swaps. I still have the 28, 50 and 135mm primes also; the 28 isn't needed for the Oly kit but fast 50 and small 135 could see some time there. The 300mm mirror lens might be quite fun as well!
