When given an input of 0, this program produces itself. When given a different number, it produces the quines in the format
&quot;[0#34o+]l2:)&amp;o@.0*74#!,!?:o1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 #_4F.~6.@1~0@D~FJR'!+!7,++tttt=++%88-$@,kJ'$.k+bf:k+bfj*a!:&amp;,k-.#!0+df+c+f7

Where the 1s are the input number. Since there are 26 copies of the 1, this makes each quine distinct at least \$bytes/4\$ Levenshtein distance. The quines are entirely interchangeable as no program actually cares about the number part. I might see if I can add some more 2D languages to this (I'm thinking Cardinal Gol&gt;&lt;&gt; next) Don't have one in mind right now.
