No they will not fit . I am sure that something could be done, but it would require extensive modification.
The BM59 is based on the garand and even some mods have to be made for a garand to fit in some of the folding stocks ,due to the follower rod on the garand hiting wood on the Bm59 stock. It is a non issue on a standard Bm59 stock or on a Nigerian stock ,but is an issue on the folders.
