Prime focus

Can't get focus on a Dob with a low profile focuser and short 2" adapter. I've read you can achieve focus by moving the mirror up 2". Can you accomplish focus by shortening the tubes by 2"? And if this will work will you lose the ability to manualy view thru the scope? Any help appreciated, Ernie
