I cant comment on the Killis as I dont know much about them but a quick google places them in a lower temperature which would clash with the Blue Rams also - but as said above the Danios and Rams wont work also the Gourami wont be able to deal with the high temps for the Rams either.
I would probably look at swapping your Blue Rams for Bolivian Rams or Nannacara Anomala would work as they both can live well at 23/24c and instead of Danios go for Micro Rasobra like Chilli Rasboras or Galaxy Rasboras. And have a look at a stocking of something like
2 Gold Australe, Aphyosemion australe
2 Bolivian Rams
3 Sparkling Gouramis
10 Chilli Rasboras
And then IMO you still have a nice amount of space for more fish - you could probably get all 6 of the Sparkling Gourami that are in the deal
Some Cherry Shrimp and or Pygmy Cories would work well and fill out the bottom of the tank nice or a group of 5/6 Panda Cories again doing well in 23/4c.
