IBM *has* been imagining this for a long time, too. The good thing is that the cold compresses have been effective and the migraines don't occur as often now as they used to.... The problem has to do with block 3270 vs. serial NVT mode. You would enter the system in line mode and switch to 3270 as usual to get a VM logo and logon, then, by some miracle TBD, switch back to line mode (emulators aren't so good at this, btw). And then there's the whole ASCII/EBCDIC/ASCII translation thing. You really want a "passthru mode" LDEV. Unless you're connecting to an EBCDIC guest, of course.
