Yes it is certainly possible, i have done this recently myself and like
you i couldn't find how to do it in any man page. Fortunately i could find
the answer in the xorg-server source code.
You just open one of the virtual terminals and issue the VT_ACTIVATE
ioctl:
fd = open("/dev/ttyv9",O_RDONLY);
ioctl(fd,VT_ACTIVATE,10);

Well, the above code only switches the active vt...
If you want your program output to go to a certain vt you probably have
to open the specific vt and replace the stdin and stdout file descriptors
of your program with the one of the one of the vt you just opened.
But there are probably some caveats to this method, so best is to take a
look at the getty source code and maybe add your program to /etc/ttys.
