I look at it this way.
Most players acknowledge that the 3e/5e style of multiclassing encourages dips, taking 1 or 2 levels in one class to accentuate the "core class". It's generally viewed that an even level split of classes (like a fighter 6/wizard 6) will be weaker than a character with a single class of either parent class.
But, a lot of players liked the 1e/2e style of multiclassing, whereas the two (or three) classes were blended right at the start of the character; where being a F/MU or MU/Thief created a distinct identity.
So, the question becomes, how to create a system that allows for that hybrid identity, but can also be tacked on to the current class system (either alongside or replacing the 3e/5e multiclass rules) without being either too powerful or not powerful enough?
4e, to my mind, probably had the best version system with their "hybrid multiclass" system, where a character would pick two "hybrid classes" that had about half the features of the core classes. The OP is almost a variation of this, but with the twist that the player can design and size their own two "hybrid classes" by picking the which portion of the class features they want, and the exact ratio of class A to class B desired.
The other main approach is a "delayed progression", where a multiclass character will gain features of both classes at a slower rate than a single class, but faster than a pure split level in a 3e-5e MC paradigm. Generally the progression is roughly Pythagorean, where a 10th level multiclass character will have about 14-15 levels of class features.
