There’s the Elevated Kinetic Energy Test Bed, that looks like it is using a M551 chassis, which could be neat. I think it uses the same, or similar gun, as the HSTV-L and RDF/LT in the game. So perhaps a bit higher BR than what you were looking for.
The XM551 with the M68 105mm gun would be my top wish for a Sheridan variant. It would be a huge upgrade in firepower for that poor vehicle.
I’m definitely not a fan of the standard version’s 152mm HEAT-rounds. And don’t get me started on those nose-diving missiles… So getting an actually potent and familiar gun would be a huge upgrade and hopefully fill a gap.
But surely this has to be an event vehicle like the float cat. I don’t know much about the LVT, but I doubt the survivability is any good. And it’s so fat, so I don’t think hull-down sniping would be viable, plus I doubt it will be able to match the mobility of its smaller brethren. All for the sake of amphibious capability, which in this game (so far) is worth shat. A genuinely good tank; probably not. A funny obese meme tank that’s somewhat viable (unlike the FIROS); totally. Also, is there any Sheridan based thing that can shoot a dart? (eg XM578E1)

Out of the actual M81 152mm Gun-Launcher that the normal Sheridan has, probably not.
The XM578E1 round the MBT-70 and XM803 tanks both fire out of their 152mms are slightly more modified and longer-barreled for that exact reason.
There is however, the Stingray light tank developed by Cadillac Gage mentioned already earlier which does use the Sheridan chassis but with a modified turret and L7A3 105mm capable of firing the M426 or M735A1 NATO APFSDS rounds.
It would honestly be the absolute perfect 8.7-9.0 light tank fit for the U.S. and Japan (since Thailand also uses it) for those who prefer speed and a larger main gun than just a 20mm/25mm autocannon and TOWs, etc… (Edit I checked the main suggestion thread for it and saw that it’s been passed for consideration to the devs so yay :P)
