Doubt you'd be able to get those custom Ohlins without buying a Cake ..
Have seen some highly modded Surrons with the 43mm WP forks from the KTM SX85. 2018 & later are the air forks I believe. ( there's a set of 2021 SX85 forks on eBay currently )
You could also get the Ohlins STX 22 closed cartridge kit & install into the open chamber 43mm WP outers of previous years.
You'll likely need to be swapping out everything with a fork change ; triple clamps, wheel, brakes & so on.
