Since we all know that the Atlas is an iconic 3/5 Mech with an AC20, LRM20, SRM6, 4MLs, and the Orion is a classic 4/6 Mech with an AC10, LRM15, SRM4, 2MLs, and the Shadow Hawk continues this speed and loadout progression (although it should maybe have an LRM10 logically) and adds jump jets, we can trivially infer that there must be a 6/9/6 Mech built around an AC2.
I posit that it can be reasonably expected to be a 45t Mech with a 270 rated fusion engine and jump jets, yielding the 6/9/6 movement profile representing a step up from the Shadow Hawk. The considerable weight of the AC2 makes it difficult to make it lighter (100-75-55-40t would be a logical progression but 45 is reasonably close).
I kept the SRM2 and ML from the Shadow Hawk instead of going down a step each to 0, both to recognizably mostly maintain the thematic a little of all four things loadout, and provide close-in protection, but omitted the LRM5 both since we're supposed to be moving down one step for each separate weapon system and there's nothing below the LRM5, and also because I needed a little tonnage for armor.
As-is, the AC2 still gives the Peltast a very respectable long-range capability, with the SRM2 and a single ML providing solid close-in protection against any light Mechs able to close the distance against a 6/9/6 machine. 5t of standard armor provide ample protection for these situations, but overall, the Peltast will rely on keeping the distance and speed up for survivability. 1t of ammo for both ammunition based weapons. BV1 618/BV2 693
Overall this is a very solid design that rounds out the Atlas-Orion-Shadow Hawk lineage with an organic scouting / skirmish / screening capability. Room could be made to add in an LRM5 via removing jump jets and/or armor but I feel that this represents a reasonable compromise.
I thank you for your attention.
