Fritz was tested on Heinkel 111s and was slated for use with the He-177, but it was only used in combat on the Do-217.
However...while on the subject of Ju-88s, a Mistel might be fun*. We have Ju-88s and we have 109F-4s and 190A-5s *(Note - I said fun, that's all).
Pilot the '88 into the target, when it explodes, you're spawned into the level-flying 109. Your 109 gets downed before you crash your 88, tough luck, you're dead.
