No chance unless it comes as an early release 2021. Also, in 2017 Rocky Mountain made all of their bikes going forward "BC Editions". Old platform instincts got overforked and bigger wheels, all Elements except XCO (which wasn't around in '17 anyway) got bigger forks, altitude came out with 36es across the lineup.
New BC editions seem to run longer travel now, which I'm not sure how that would go for an element.
The Element is the original downcountry bike.
So part of the reason I love rocky mountain is you can go down the "super not approved by rocky mountain" rabbit hole. The current Element runs a 6.5x1.5 shock, which is approximately 165x38 in metric. 165x40,42.5, and 45 are all sizes that exist. So, theoretically, you could use an OEM spec rear shock at let's say 165x42.5 and make your OWN BC edition element. You'd be looking at somewhere in the realm of a little over 110 rear travel. Exact number is unknown because you can't 100% math it out as the axle path is unpredictable outside the intended range. IF a big bottom out event didn't cause a reasonably sized tire to slam in to your seat tube, you could totally run a shock like this and not alter the stock geometry given the same eye to eye.
Moveover, Elements run zero stack headsets, meaning that there's a press in cup. What that means for you is that you can totally run a angleset in the frame. Anglesets will slacken the head angle while lowering the BB, shortening reach, and steepening the STA. You can use this as a tool along side fork travel and ride-9 to create a super unique Element that is the epitome of 2019 downcountry.
Given that they've played the longer shock size game with the Altitude, Thunderbolt, AND Instinct, they've probably tested it and maybe their product manager will come in here and tell me I'm an idiot. They do browse this forum.
