comment Calculating periodicity of a pseudo random number generator (Middle-square method)
This question is squarely off-topic on crypto.SE because it is about a non-cryptographic Random Number Generator.

comment Reordering non-block-aligned parts with DES in ECB mode
Yes, with the assumption of a known plaintext block common to enough instances of the problem to make a precomputation worthwile, what you are describing is feasible. However that does not apply in the situation of the question: there is no indication of multiple instances, and I see no hope to find an existing rainbow table that applies, for we need a different table for each known plaintext block.
