I don't think this constitutes a dialect. It's not distinct enough from Standard English. Believe me, I've been to Miami plenty of times, and I've heard the typical "spanglish," it was fascinating to hear a group of friends rapidly and fluently switching between English and Spanish. But the English and Spanish were distinct. And the two languages are similar enough in their structure that when things get calqued there is often little to no loss of meaning.

Hinglish, which is a language I've learned (well, I learned Hindi and I grew up speaking English) is a radically different dialect of English. Hindi, like Spanish, is also in a lot of ways very similar to English. But there are enough differences where the logic of the language, when used by Hindi speakers, changes enough that in order to understand the meaning of any given phrase one often needs to know both Hindi and English, even if all the words used are English. What one must understand is, all English words are part of the lexicon of Hindi (as are all Sanskrit, Persian, and Arabic words--in fact, alongside the major South Asian literary languages, any language spoken in the region where one is speaking Hindi is a language that loan-words are pulled from. Hindi is more a framework than anything else), such that you can speak Hindi only using English words, and its still basically Hindi. If you don't know Hindi, even if you know every word, you might not understand the meaning of the sentence.

I understand the impetus but linguists for whatever reason are oftentimes politically motivated in this sort of social-justic-y, milquetoast liberal progressive way that stretches the limits of what can and should be rigorously defined as a dialect. AAVE is a real dialect, and there are many different registers of English in the world. I really don't think this rises to that level.
