Due to some bundle size restrictions, we are looking at converting some runs over to use bi-directional fiber sfp's

anyone aware of a vendor that makes an inline bidirectional amp for this sort of application? I did some digging but 
either they do not exist or my google fu is weak today.

So you really just want the 20km optics:

GLC-BX-U20
GLC-BX-D20

Most places also make 40km and 80km optics of the same sort.
