That design is for 18 years after the start of our game, Ruby...though it's custom, so Jack could certainly rule it's available.
Still, if you want to do something light and fast, why not take an actual battlemech? They are much more survivable than a vehicle, where by all rights, one single stray LRM missile could blow you the hell up with a lucky shot/roll. I mean, there's a Davion Locust
variant that mounts two LRM 5s...not to mention, most combat vehicles are designed with the idea of a crew, at least 2 or 3, whereas mechs are built for a lone pilot.
Do what makes you happy, of course, I'm just wondering why you're so keen on playing with handicap, Ruby?
I think you're previous idea of a VTOL for scouting would actually be a sweet idea, if you don't want to play a mechwarrior for whatever reason. Sure, fragile, but you want speed and maneuverability, that's your bag. Being able to go up also means you don't have to maneuver around terrain, which makes staying at long range much, much easier.
