That is about as close as you can get them and still be able to slip on
the "average" BNC cable.  Any closer and the outer ring of the cable may
bite into its neighbor when rotated to lock.  At that spacing you can
grab from the top and bottom but not wrap your hammy little fingers
around the whole connector.  Fine for a single row but don't space each
row at 20mm unless you plan to supply a tool for inserting and removing
the cables.  They do make such tools by the way.

If you are going to have a large array of connectors, consider switching
to SMA, SMB, SMC, MCX, etc.  SMB works pretty well if you don't need to
change cables frequently and can live without the mechanical (thread)
locking of SMA.  The push-on, pull-off is nice, no rotating or other
alignment issues.  But it is easy to destroy a cable by yanking on it or
smash the center pin if you get to aggressive with a poorly aligned
connector.
