if they had continued producing saturn v then the int-20 had a decent case to be made for it. the production lines for the saturn v were expensive to maintain and they were going to be sitting idle most of the time so making a few extra S-ICs a year didn't cost all that much extra money compared to. boeing did a study in 1966 that concluded that making 3 saturn Vs per year + 3 int-20s per year while closing down saturn IB production would actually be cheaper than making 3 saturn Vs per year + 3 int-11s (here called the uprated saturn I w/ 4 120" SRMs). pdf if anyone's interested: https://a.uguu.se/yTcwUJMe.pdf
but, if you're killing saturn v anyway then making int-20s for LEO missions would be way more expensive than just using titan IIIMs.
