Being your familiar with ProTools, im gonna guess you've heard of or tried Reaper DAW (sorry can post urls), if not they have a free fully functional version you could try. Ive recorded 8 tracks at once (drum kit) on separate channels, you could do the same for foley. After you can mix that down so a single file or keep it as separate files. Being Reaper is a DAW, you can also process fx, panning and everything else also.
{EDIT}
Reaper does have a built in video player.
Ive only used the video player a few times for short clips (1-2min) in order to add foot steps to footage with a midi keyboard and a vst plugin. Don't know how well it would hold up for longer footage.
You can also create your own vst and make your own "sound library(s)".
Example: i made one for house doors with a single sound sample, then its pitched (deeper and higher) depending on what note is pressed on the keyboard.
Just food for thought.
