It sounds like it might be comparatively easy to convert an Electra to
a P-3, or vice-versa -- it's hardly unprecedented to slice a fuselage
and insert a plug or take out a piece.  In contrast, converting a 707
to a KC-135 or vice versa would be a massive undertaking, creating an
almost entirely new airframe.

Perhaps a better comparison to the Electra and P-3 Orion would be the
707-320 and the E-3A AWACS, which are essentially the same airframe.
I believe some of the E-3A AWACS aircraft may even be converted 707s,
though I may be getting confused with the E-8A J-STARS, all of which
use converted commercial 707-320 airframes.
