Manual cameras are little more than fancy light tight boxes fit between the film and a lens with a shutter somewhere in the mix.
Ultimately it comes down to yes you can... but the real question is whether or not you should.
What features and functions do you expect out of your combination, and what are you planning to use for a donor body on this project? And what are your technical skills for a project like this?
If you have a working lens without a working body, a serviceable body without a functional lens, and the skills to merge them to the functional point you're after, then why not? If you're missing one of those three things then your project is in a rather questionable state...
[You may be better off looking for a Rolleiflex Tele, or maybe a Mamiya TLR if you're not interested in dropping as much cash.]
