I would suggest, for a two-view print, you use a clear/opaque linear GRATING over the photo paper, instead of the lenticular lens sheet.

While you would not have to reposition the enlarger between views, you would require three things:

  1. A grating that matches the pitch of your intended lenticular sheet. You might be able to print one with a quality inkjet printer using black pigment (or deep red dye) on clear plastic.
  2. A method to re-position/shift the grating precisely by one "line" between the two printing exposures.
  3. A method to maintain the grating completely flat against the entire surface of the photo paper. This may be the toughest task unless you use a sheet of high-quality flat glass and a flat easel.

Perhaps a good method would be to adhere the grating to a flat glass sheet.

As you are probably aware, good lenticular prints are made with a multitude of of views (four, or even more views).
