Yes... I'm kind of deliberately being colloquial on account that I have no real expertise and but the most basic understanding of the subject.
Again.
The first 'Life' is hypothesized as to being RNA.
With our current form of 'Triple base paired DNA' taking over/supplanting the RNA.
However like the scattered remnant examples of monotremes, marsupials, Wolomi pines etc RNA still lingers about.
Another thing. All life on Earth uses a triple bonding pair of genetic molecules.
You could get away with two base pairs. But this would lower/limit the amount of protiens you can create.
Or you could have four or even five base pairs.
Heck, pretty sure if you went up to five you'd be able to create every protien currently known.
Cheers.

Idk I'll have to look up a paper on it later, your metaphors are throwing me off lol. If RNA smooshed together to create DNA, that's a different idea from DNA emerging separately and eating RNA. I also wouldn't consider RNA a stub within DNA replication, so.
@Mister Agenda
I'm also curious to know if you think evolutionary biology could indeed distinguish separate lineages derived from distinct origins, that have otherwise similar structure? In other words, if two organisms share gene A, is that enough to know they absolutely have a shared origin? There are only so many elements, and perhaps life can only emerge in so many ways. Crystals don't have a shared ancestry, but they all have a shared structure. I would assume that if life emerges multiple times, it does so with rather similar structures. My point is, I think shared origin is an assumption evolution broadly makes. I'm less certain it is a fact that evolution can establish.
