In theory yes - that's what the SHARED verb on the .stg file is for. The idea was to only have one model loaded, and then place it multiple times in the scenegraph. However, IIRC there was an issue with memory management in OSG which meant that when a tile containing SHARED entries was unloaded, it caused FG to churn for a while updating various pointer counters. I don't think this was ever resolved, so currently each SHARED instance is loaded individually. While this approach would reduce RAM usage, it would be at the expense of frame-rate, as the 50000 models would still each require OSG state change.
