That was the plan, but step (4) really seems problematic.

Tag every term with its length in tokens. :)
Index at these positions.
Pos0: a ab abc abcd
Pos1: b bc bcd
Pos2: c cd
Pos3: d
Create a phrase query that when it encounters ab => { tokenlength =>
2 } knows to look for something at position 3.
