My concern with the LiFeP04 batteries concerns my hangar arrangement. Two
of my three batteries require tools or removal of the tail to get them out
of the glider so my glider stays connected to "smart" chargers continuously.
At present, I'm not comfortable with leaving a lithium battery connected all
the time. Is it safe as with the AGM batteries?

Seems a bad idea to me.
As Dan suggested, there is no need for all this with good batteries.
A couple of Tenergy or K2 12V 10A/H LiFePO4 would be the best solution. You
can do 1000k with a VGA moving map display and transponder (plus the usual
assortment of crap) running from pre-flight to flight download. The
batteries will still be above 12V afterwards.
Besides the aerodynamic drag and storage problems, what time and money are
involved to replace the canopy after a bad deployment or retrieval of one of
those generators? It will happen sooner or later.
With that consideration, even phosphate batteries are cheap.
