According to Heyman, Nats are a player for Hand now. The question is money (obviously).
I really don't see how they can make this move, regardless of how good of a fit he is.
The Nats still are almost $27MM below the luxury tax threshold. They can afford to give him 3 years, $30MM, which is the high side of estimates, if they think he's worth it. They'd still be able to sign an Alex Avila or Tyler Flowers for $4MM if they wanted and have a lot of room for mid-season additions if they needed it.
I could see them giving Kieboom another shot and more or less leaving the lineup as is now. Best case scenario is that it clicks for him. I expect the Bell/ Zimmerman combo at first to be productive offensively, so I think that is your Soto protection. NL East, other than ATL (Fried and Smyly), is pretty heavy on righty starters. Righty starters killed the Nats last year with Thames just not ever playing well and nothing to fear from Garcia. Having Schwarber and Bell with Soto helps, and Castro hits righties pretty well, too, and Turner hits everybody. I would like La Stella as one more position player for OBP, but I hope it isn't a fatal weakness. Against lefty starters, Zimmerman plays and crushes, and, surprisingly, Gomes does very well.
