Honorable mention for the 20-ton bracket goes to the Hornet (which would have three variants (the HNT-151, HNT-152, and the HNT-171) as of 3051) and the Mercury (which would have the MCY-99, MCY-98, and MCY-97 variants, but the first two would require MASC to be implemented).
For the 25-ton bracket, there is the Mongoose, which could have the "basic/standard" MON-66 variant (uses Endo Steel, FF Armor, and Beagle), the MON-69 variant (-1 Beagle, +1 laser, +1 SRM-2), the MON-70 variant (-1 Beagle, -1 laser, +2 flamers), the MON-67 variant (no LosTech, + armor), and/or the MON-68 variant (no LosTech, Engine rating downgrade, mounts a single LL in the RA).
It's also got the digitigrade/"double-knee" leg design.

The 30-ton bracket has a number of options:
- the Hermes (with its HER-1S, HER-1A, and HER-1B variants; the HER-3S/3S1/3S2 variants would require MASC to be implemented)),
- the Hussar (with its HSR-200-D variant, HSR-300-D variant, and HSR-350-D variant), and
- the Javelin (with its JVN-10N variant, JVN-10F ("Fire Javelin") variant, and JVN-10P variant).
For the 35-ton bracket, there are the Firestarter (with its FS9-H variant, FS9-S/S1 variants (the latter of which replaces the former's BAP with a GECM suite), FS9-K variant, and possibly FS9-M ("Mirage") variant) and the Wolfhound (with its WLF-1, WLF-1A, and WLF-1B variants), with honorable mention going to the Panther (which would have three variants (the PNT-8Z, PNT-9R, and PNT-10K) as of 3051).
For the most part, everything else is already in-game, Clan-built, Macross-derived Unseen, and/or doesn't have 3+ variants generally available circa 3050.
Thoughts?
