I would think I'd stick with this "Lori" concept.

Fancasting: for a teen/young adult version I think everybody has it nailed with either Sarah Catherine Hook or Talia Ryder.

Or, as I'm looking up young popular people under 21 there's someone named Kristina Pimenova who is a model that looks the part.

Half Kryptonian.

Lori pushed against the train, her shoulder lowered into it as her feet burned against the rails. “Aaaaargh,” she grunted pushing with full might, “guys I can’t... I can’t...”

“You’ve got this Supergirl,” Wally encouraged over the comms, “you’ve got this, we believe in you.” He was busy, his fists connected with the drones one by one. Moving so fast that gravity didn’t have a chance to bring him back to the ground as he kept moving.

Half Human.

“You can do this, Lori,” M’Gann instructed, “you have to, there’s no one else who can. Kara’s off-world helping the Legion and Conner’s with Clark and the Teen Titans.”

Roy Harper’s arrows hit their marks targeting the terrorists inside the train, “you got this, c’mon now, you can do this, we believe in you.” He looked over his shoulder as Thea’s arrows crossed paths with his. There was a sudden jerk and the two were thrown forward losing their bows in the process. 

Lori’s back had been pushed well into the front car, smoke billowed from her feet and she looked down at the fall that would’ve been. She swallowed hard and closed her eyes. Her job wasn’t done yet, she turned around and pushed, one step then the other. “You’ve got this kid,” Maggie’s voice now over comms, “come back a few blocks. I’ve got Harbor PD standing by, and a squad of happy NCPD officers ready to take those terrorists.”

“Thanks, Mags.”

“You got it baby Danvers.”

One step then the other.

The train was moving backward, rolling along the rails. The night was cold, bitterly so, but it didn’t bother her. She had a job to do, a name to uphold and a legacy to forge. Her red cape moved with the wind, black hair whipped back as she pushed the train. 

Roy and Thea had managed themselves back to their feet and hauled the terrorists into one car. “Good work, Supergirl.” Thea knew what praise meant to a new hero. “Pizza party back at the training center, guys.”

“Oh, can we get it with bacon?” Wally asked over comms, “actually, I’ll get it from Coast City.”

Half Kryptonian.

“I’ll help you, heaven knows that between you and Lori we’ll need at least ten dozen,” M’Gann added.

Half Human.

Lori chuckled, “hey now, pushing trains is a real calorie burner.”

Kara could hear their daughter fidgeting in her room, she was excited and nervous for dinner. She walked around her room giving herself small pep talks that ‘everything will be perfectly fine and moms will love him’. Lori’s enthusiasm made Kara feel giddy, they were finally meeting the boy who’s been responsible for their daughter’s crazy behaviour the past few weeks.

“I know you’re listening in on her.” Kara felt the knowing stare of her wife.

“Lee, she’s happy. We should be happy for her too!”

“You’re not secretly listening to her because you’re happy about all this. Now dry the dishes, I’m running out of space.”

“Of course I am!” Kara resumed her chore, “I just want to be sure that she’s not feeling bad about… you know…” she gestured a half dried pan towards Lena. It earned her a well-deserved splash of soapy suds.

“How dare you, Kara Zor-El. You are just as apprehensive about this as I am, the fact that you have taken to playing good cop changes nothing.”

“Well… alright. But we should at least give them the benefit of doubt, don’t you think?” She watched Lena close the faucet and grab another dish towel.

“There will be no need for that, if he has even one stray thought I sw-“

“Babe.”
