Paris and Jackson are at the same level, in Low-A. So both of them possibly. Vera is probably 2025ish.
Honestly there's always Michael Stefanic who could play 2B and Fletcher at SS as well.
Stefanic is currently on a 15-game hitting streak for Triple-A Salt Lake and overall is batting .331/.406/.473. He has shown exceptional barrel control, rarely swings and misses, doesn’t chase out of the strike zone and has shown growing power, impressing even in the context of his hitter-friendly environment.
