If it were me, I'd buy a dedicated RTA or RBA. Honestly, I just haven't had a great time with "decks" built for drop in coils, I find them small, fiddly, and not the greatest performers as generally, tanks with drop in coils that also have a deck are more geared to run best using the drop in coils.
However, I am not the most stellar of build people and I have a fine motor tremor, so your experience may be completely different... I do think dedicated rebuildable atomizers are the way to go though, if you want to be building, just generally, one will tend to get better flavor.
However, if this is your "dream" setup, well, who am I to judge, although I also don't have much to offer.... So, I'll just wish you luck in your endeavors.
