That hole looks like it is larger than 1/16th maybe 5/64th? That would be the next common drill bit size up...
I would try to put one coil in front of each airhole maybe a mm or two just off the ceramic deck. I forgot to mention this is all speculation for the RM2 since I do not own one. Moving the coils further from the posts and closer to the airholes will also help to increase the resistance of your build, not much but it will raise it, just be observant of hot legs, they dont happen often with a good micro coil but they can happen.
The lower resistance will increase the vape temp in a small chamber RDA. It can affect taste both for the better or the worse depending on chamber size, wicking and airhole size, coil placement in relation to airhole and ID of the coil.
For example I have been playing with builds in my Atomic RDA and using 24ga. Typical go to build is 0.20-0.30Ω using a 1/16th ID and 7/8 wraps (SOLID VAPE using the 2mm airholes plenty of V/F/TH!!!) but if I increase the ID to 3/32 or 5/64th I would need to lower the # of wraps to achieve a similar resistance but when doing so I tend to get less flavor similar vapor production and an increase in TH compared to my typical build.
Its fun to play with coils as long as you are actually happy with the results. If you are unhappy with any of them your frustration will ultimately be your undoing and lets face it stress free vaping is why we all have REOs
