To reduce mount load, I want to replace some counterweights with scopes.. Canon is 5.5kg, Rubinar 2.7.. so some more weight should be added at the shaft or Rubinar should be mounted further away from shaft for proper balance.
Did anybody tried something like that?
Of course, collision with pier could be an issue, but I am trying to be careful with that anyway, my mount is not fully automated.

Hi Bojan,
I think it's a
great way to more fully utilize the drive capabilities of the mount rather than waste it driving too many counterweights as well potentially offering the benefit of increasing the
effective payload and allowing you to use your EQ6 and not have to go for a larger weight class mount.
Of course, as you already mentioned, this is all at the expense of much greater care being required when slewing, during go-to or positioning the system for fear of a collision. Also using a pier, as you are doing, gives you more clearance than a tripod.
Just a thought: If you only wanted to add say one extra optic, and wanted an easy/quick&dirty mod you could consider mounting it to a counterweight placed at the end of the counterweight shaft and thereby have an intrinsic angular adjustment built in and also retain the ability to shift the counterweight/ota assembly for balance by moving the entire counterweight shaft in/out. Your way fashioning a new nut etc, is of course more rigid, but quick and dirty may be of some use too.
Best
