Yeah, I thought your original plan was High Roller brought the Precure in from a time when they were at their strongest (meaning this version of the Sporty and Dino Spirits team came from some point during their respective seasons). What you have is fine as well though so it's really up to you.

As for how to tie it back to Dino Spirits, maybe at some point have High Roller escape to the past in a last ditch effort to attain his goal. Aya winds up jumping in after him alone and winds up arriving one year prior during the Dino Spirits finale. Passing through the portal seemed to have an effect on the Prism Cards which were now glowing brightly. Meanwhile High Roller throws out a card, creating a Dark Matter monster to ambush the Dino Spirits team (as alluded to in my summary of that season's finale a little ways above). Seeing this, Aya pulls out on of the now glowing cards and slashes it, suddenly transforming fully into Cure Black (complete with her voice changing). She's of course excited by this and leaps into the fray.

After a retread of what happened in Dino Spirits Aya makes her exit and runs into High Roller, they fight for a bit and Aya manages to force him to open a portal, shoving him inside and sending them both back to the present.
