I think it is a flawed idea to replace a system used by over 50million people. You can't beat that inertia.
That's true, but I don't have to sway 50 million opinions, just the hundreds that play epic level, who already understand the WotC system has flaws at epic levels.
What is the benefit of having two CR systems? How can that possibly be a good thing. Your system will not overpower the existing one, it just can't IMO.
It only needs those few hundred or so DMs/Players to see the benefit.
EDIT: I don't mean to sound so harsh - and this will be my last push for using the existing paradigm
Push away my friend - I am thick skinned and I like a good debate. Don't worry about hurting my feelings.

Not sure what you mean by the CR messing with the encounter building. The encounter builder uses XP, not CR - this is particularly important with mythic monsters. They are related, but also different. And the encounter builder actually does work (for a certain set of players). The bigger issue is the names they gave the levels of difficulty. What they call "deadly," doesn't fit the definition of deadly as written or in the math, IMO. However, if you make a truly deadly fight (75-100% of your daily XP budget) then a lot of the misconception of the encounter builder goes away (in terms of deadliness).

EDIT: I can't remember if I showed this to you before, but if you use the XP budget to make a truly deadly fight as shown in:
It's not Deadly, its Epic! You begin to understand that a solo fight can be deadly in 5e with the RAW math. You just have to use a lot higher CR monsters than you would think.
Notice a CR 24 Ancient Red dragon is an epic (aka deadly) encounter for 4 lvl 15 PCs. It is not a challenge for 4 lvl 20 PCs like some people think.
To be honest its no skin off my nose for me just to use WotCs crazy numbers. I don't see the big hullabaloo.
By this math Strahd should have been around CR20-21 in CoS instead of CR 15.
When I use the term epic/deadly I mean a 50% chance of a TPK or there about. You can do that with the default WotC CR and encounter building rules - you just need to look at daily XP budgets, not per encounter budgets.
I do think that is a good idea. I've abandoned CR really for my epic monsters. I say for each exalted tier above, it is equivalent to 3 of the tier below. So an exalted rank 2 monsters it equivalent to 3 rank 1 (demigod) PCs (or monsters).
I don't see the massive difference between changing the Daily XP Budget and fixing monster CRs. But I'll have a think about it.
