xterm should have VT52 emulation, at least the man page on my system says:

       o   VT52 emulation is complete.

But looking at CTRL+{LEFT,MIDDLE,RIGHT}_CLICK menus didn't show a toggle.

The VT100 sequence to enter VT52 mode seems to be <ESC>[?2l
you should be able to send it with echo.

Then <ESC>H<ESC>J should clear the screen.

NOTE! The ANSI command prefix <ESC>[ will put a real VT52 into "hold
screen" mode where you need to press some (scroll?) button to allow
new lines to be added at the bottom of the screen.  Ask me how I know!

Well, is there no end to fascination... That 'worked' in that I was able to do this in n xterm on my mac:
printf "\033[?2l"

which changed the size of the xterm window to 80 chars wide... then:
printf "\033H\033J"

which cleared the screen as you said it would.

But, then, I telnet'd into the the v7 instance and set TERM=vt52, etc.

Now vi gives this:
Y7 HJY- ~

        ~

        ~Y,

However, I should note that v7 doesn't seem to process escape sequences, either with a pristine instance or my fully configured instance...
echo '\033'
