Sounds like a great idea, so long as you put in some criteria.  Try to pick "well made" maps (not lotto maps, for example).  I would not play anything rated under 3.5 if I were you.
Also, try to play settings that reflect the map's intent.  Some maps are strategic, some rp.  I would suggest if there is a template in the map description, try those out first.  There isn't much point to playing the wrong type of game on a map.
I don't have time to play (sounds like you have enough).  But I will certainly read whatever writeups you have.  How will you choose a map?  A nomination system with votes?
Also, it would be cool if you made a web page for this, so that it does not get buried on the forums (and just update this thread with progress from time to time).  Something like what I did for our clan (but with writeups of course, links to games perhaps):
