Would a MultiTree be a good middle point of DAG and Blockchain?

I know how the bitcoin blockchain works, and pretty familiar with DAG (directed acyclic graph). What I am curious about is if you mixed them, would there be any issues, or would it just make confirmations quicker?

1. Is this (b) a little better for confirmations? As I'd cut a block time x 3 (3 mins) and theoretically quicker confirmation counts?


2. Is there any downfalls to using B instead of A or B?

What I mean is better explain with the below picture:

• A = Block chain


• B = (what I think may be called a multitree?)


• C = Dag
