I’m actually going to test some professionally-lubed U4 Bobas using lighter 55 G springs, but I wasn’t planning on doing that anytime soon. [I have them now, though.]
To answer the OP’s question, you can use the other OUTEMU custom silent stem, the “Silent Sky / Silent Forest” stem that is also known as “Silent Tactile.”
It is meant to be about as tactile as an Ergo Clear, and while it does not feel exactly the same, it is about as tactile.
You can run them in a fairly tactile housing at around 62/63.5 G, or a less tactile housing [like Cherry] at 60 or even 55 G.
They were originally meant for the teal Silent Sky housings, but those housings are outdated. In those housings, they were fine and poppy and tactile at 62 G using the default springs. You could alternately use the OUTEMU Blue Ice housings if you wanted something a little less tactile and pingy [get them while you can at pennies on the dollar!]
I found a good combination to be Silent Sky stems in an MX Clear housing with 60 G springs. It’s poppy, and a little more tactile than Browns.
It’s either that, or try to reduce the tactility and increase smoothness with U4 Bobas. U4s will function at 55 G in the Boba housing, you may have to mess around with it to make that happen. Interestingly, the Silent Sky stem needs maybe 68 G for full function in that housing, even though it is less tactile. [You should be able to get away with 62 G]
