I was re-thinking about this thread and I realized something. No doubt obvious to some, but somehow I hadn’t realized the full implications. Maybe it deserves a separate thread but I’ll dump it here for now…
So… what you’re doing in this build is a pure EK all the way until level 20, which gets at most one 4th level spell at level 19, but the big unlock is that as soon as level 7 you get this once per short rest level 4 slot (and eventually level 5 slot).
Now, I know you dissed theory crafting in the OP and I can appreciate your sentiment
… but I still want to indulge in a bit of it 
Before this Potent Dragonmark feat came out, it used to be the case that the only spells you could ever have prepared were those:
1. Coming from a pure class
2. Coming from feats (level 1 or 2 at most)
3. Coming from a species (e.g., High Elf, again level 1 or 2 at most)
So if you multi-classed, you could get higher slots, but not higher prepared spells. But Potent Dragonmark breaks these precedents, since at the cost of 2 feats (including one origin feat) you get a bunch of prepared spells, all the way to 5th level.
This means for builds which depend on a few specific high level spells (such as the one in this thread, with CME) you need not actually take 7 or 9 levels of a full spellcasting class to get them, but you could still get plenty of high level slots to pump into those spells even though none of your classes is actually high enough level to let you prepare them.
As a dumb example, let’s think of a fairly innefective build which nonetheless gets 20 full spellcasting levels: Druid 4, Cleric 4, Wizard 4, Sorc 4, Bard 4. These classes allow preparing only 2nd level spells, and yet, with Mark of Storm and Potent Dragonmark, the character can cast a 9th level CME! This build can not only cast a 5th level CME once per short rest thanks to the PDM feat, but it also has a whopping 12 slots of level 4 and above per long rest that it could cast CME with! In a sense, it’s a one-trick pony, but that pony can really do its trick over and over again
I have a feeling this will open up the possibility of new multi-class builds that were not possible before. I have not thought of what these builds might be exactly, but I do think it’s kind of a mini-breakthrough in theory crafting.
Again, apologies for hi-jacking the thread and for those for whom all that was already so obvious
