Yes I experimented with this sort of thing domestically around that time.
However a huge number of mono recordings by emi and Deca and polydor were
made using delays and naff frequency shifts that all sounded like you had
a bad head cold in stereo or like it was being played in a subway in mono.

You may be right about the other labels but as far as I recall,
the Decca classical labels never did what you describe. Hence
our need to find an alternative.

The best effect i had was with small amounts of reverb, but different on
each track. Sadly though the mono in such cases did not sound like normal
mono as there were frequencies where the differing reverb cancelled and
gave the impression of notch filtering.

Total compatibility in mono was paramount.
