Not sure the average mount and guider for the OP's DSO requirement would compliment such a plate scale...
For planetary/ solar/lunar using a fast frame camera and "lucky imaging" it may be feasible.....

Your optical maths is obviously correct but here’s some of my recent images captured with BYEOS Planetary mode from Bortle 8 Sydney average seeing with my 6” f6 newt , Canon 600D , 4x and 5x Powermate and only 45 to 60% of the best 1500 AVI frames chosen in Autostakkert 3 and some fine sharpening in Registax 6. My Canon 600D set at 5 x zoom achieves close to 1:1 pixel resolution then I add the Powermate to increase my focal ratio accordingly to the seeing
Note: Mars was in the middle of a huge dust storm so poor clarity
