comment Grothendieck's Period Conjecture and the missing p-adic Hodge Theories
representation is abnormally small (compared to the full motivic group) and try to work from there (one can find examples among abelian varieties). Another question is whether you should restrict to isomorphism respecting the filtration on both sides (as I think you should).

comment Grothendieck's Period Conjecture and the missing p-adic Hodge Theories
Will Sawin, first of all, thank you for this interesting (but hard) question. My impression is that part of the difficulty stems from the fact that your analogy is perhaps not so close: a closer analogue might be the collection of all comparison theorems between étale cohomology for each $p$ and de Rham cohomology for a variety over $\mathbb Q$ (rather than the single comparison theorem for a variety over $\mathbb Q_{p}$. In that case, one recovers I believe the full motivic group. As for your precise question, I guess one can take a variety over $\mathbb Q$, select a $p$ such that the Galois
