Question Cutting down Newtonians

I've decided to take the plunge and cut down my Newt (well - soon anyway!) for imaging.
If I move the mirror up the OTA up by 35mm, everything will be OK for visual by adding a 35mm extension tube in the focuser - right?

(I realise there could be some vignetting if secondary not quite big enough)

If it all turns to custard visual wise I guess I'd have to get a 12" anyway....
