    Sure, but beware of one thing - the longer times you have, the greater is the danger of vibrations introduced by these falling beasts. Especially with long focal lengths lenses where one is more tempted to use these shutters.
    Thanks goodness Packards are not limited to nearly horizontal camera positions only with their vibrations...

    You could make a device with a variable slit width and a scale that gives proper setting for a desired shutter speed.

    You could also make the slit with vertical nylon netting inside and use the lens with soft focus effect... ;-)

    You could also use the slit with normal nylon netting inside (of different, interchangeable thickness) and use the shutter as ND filter... ;-)

    You could also use the slit with nylon netting filling a circular area in its middle (attached on both sides with a hair thin thread) and use the shutter as a vertical central filter...;-)

    You could also hang the slit plate on a thread and lower it at the speed you desire (counting Mississippis...) to create longer exposures...;-)

    You could also hang a thread on the lower part of the slit plate and pull it down by hand to create super quick speeds (for those luminous Aero Ektars with no shutters)...;-)

    You could also attach the slit (always by the mentioned thread...) to an animal trap and use it as animal actuated shutter...;-) (Heck, leave the camera in nature, take a nap and and let the wild bird take its own picture!)

    And yes, with today's means you could also use the oscilloscope (see Wikipedia for that beast) to exactly measure the inaccuracy and unreliability for which the same constructions were left 150 years ago. This Holy Grail of amateur inventors is still full of potential. Nylon roll bearings, modern mineral oils could give a new life to the guillotine shutters.
    Heck, you could also put a rack and pinion on the side of the slit and with a simple spring device power the slit so that it would work even with cameras that stubbornly deviate from the max 15 horizontal inclination. The sky is the limit here... I just hope that one day somebody will not come to announce that now you can add a shutter to your pictured scenes by the Photoshop...;-)
