ok - sorry for the entry level question. i am brand new to film and LF

I have a copal 1 210mm sinaron s 5.4 lens.

i am looking for something wide - i think around a 90mm. if i buy something that is a different copal are the lenses interchangeable? I think i'll need a new lens board, but aside from that can i swap them out without adjusting?

thanks so much in advance
