I think trying to solve issues in the setup of and apparatus used for a presentation by optimising a file is a complete waste of efforts, in many less than perfect setups there is no possibility to succeed.

A major building block of access and assistive technologies is that a user can adjust the presentation to her needs. There is no way a slide presentation presented through a video projector can be adjusted to an individual's person needs without disregarding the needs of others.

To me it seems to be a much better approach to use alternative options in the presentation setup. One such option could be to use ad hoc screen sharing in some fashion. Options to do this are VNC (screen sharing over the LAN network, available in a couple of freeware options), web meeting or webinar solutions (GoToMeeting, WebEx, or the free of charge Google Hangout On Air, etc.). Low vision users for example have essentially the same display quality as if they viewed the slides on their computer or tablet, they could for example zoom in to enlarge portions of the page/slide.
