This is what I found.

A new OTA is 365 Euro. See

You could buy another OTA for less than the Feathertouch! (Freight may be more though).
Note although ideally any new focuser is the same length you may have room to move in back focus with something different. You would have to measure at what point your current focuser is racked in for every eyepiece and accessory you own and are ever likely to own (the latter more difficult) and compare against any new focuser.
A 200mm Newtonian would give you a considerable boost in light gathering capability. Note though a Newt on an EQ Mount without rotating rings can be cumbersome as the eyepiece can end up in all sorts of positions including facing down (at an angle). Rotating rings are expensive though.
My first telescope was a 6” f5.5 Newtonian on a Vixen Polaris Mount (with extra counterweight). I got used to the awkward eyepiece angles but I didn’t have any heavy eyepieces back then to be worried about them falling out. There was no compression band on the focuser or safety undercut on any eyepiece either that I had although the eyepieces were light weight. I still have and use this telescope occasionally and have changed its focuser couple of times over the years.
Note Newtonians have far less travel in their focus range than refractors so using accessories such as Binoviewers (1x mode) or even cameras is not always possible (but not impossible with some designs). Every telescope is a compromise.
