This is the right forum.

The only DAO models that can be "easily" converted (just four parts) are the TSW models.

The earliest DAO models were produced with a frame that was machined to accommodate only a firing pin safety lever on the right side and therefore would require complicated machine work.

The later DAO frames did have room for the sear release lever on the right side and the frame could then be converted to SA/DA. (Three parts: trigger, hammer, sear release lever.)

That leaves the slide.

The slides were not machined to accept a manual safety so the only way to utilize that DAO frame we just converted would be to substitute a SA/DA slide assembly.

It would work but the slide would be approx. 3/8" shorter in the rear than the frame.

So the simple answer is: Probably not what you would want.
