In that case, the Sentinel might fit the bill for a next-round Medium - fast (97.2 kph), appeared in TRO 2750, was in near-continuous production through the Succession Wars (production ceased in 3014), and has several (six, by my count) variants that could be available using standard IS tech and/or timeline-appropriate recovered LosTech.
Though, at 40 tons and not jump-capable, it would be competing directly with the Cicada.
On the other hand, three of the four thus-far-confirmed Mediums (Hunchback, Centurion, Trebuchet) are (mostly) non-jumping 50-tonners (though, the Trebuchet does have two timeline-appropriate jump-capable variants - the TBT-5J and the TBT-7M).
The Crab, yet another 50-tonner, is not jump-capable and was generally lost to the Succession Wars; the DCMS got a few from ComStar in the War of 3039, but new construction (at the Cosara facility on Northwind) didn't take place until 3050.
The Kintaro has exactly one jump-capable variant (the KTO-K), due in 3058. Other than that, 'tis functionally a Dervish minus the jump capacity.
- Crab = same as the Swayback, and very variant limited;
- Kintaro = same as the SRM Trebuchet, and very variant limited.
About the Sentinel, it could be possible (though I hope not - the mech is very weak).
