Wow, that's quite the "mission pivot".

We already have all-electric trainers like the Bye eFlyer https://byeaerospace.com/ so I can see this "working", but I'm not certain how effective it would be compared to something as well-tested as the "stealth" version of the MH-6 helicopter that's been in production for about a decade.

Additionally, the basic non-stealth MH-6 airframe and power-plant configuration has been around since the 1960s so its base flight characteristics are well-known.
